Six Favorite Reseeding Flowers

Wildflowers that reseed are a perfect plant for busy and cash-strapped gardeners. Once you get them going in the garden, they’re sure to come back for years. The trick is to deadhead or cut the flowers for arrangements while in peak bloom and then let some spent flowers go to seed.

cosmos
Crazy cosmos! Ours have been popping up in the same area of our rock garden for four years. By leaving most of the spent flowers on the plant into fall, they easily reseed and feed finches.

With that in mind, choose a few plants or seeds for your favorite low-water annual and enjoy the colorful rewards for years. Here are six favorites of mine, most of them in the Aster (Asteraceae) family:

No. 1: Cosmos

Start with annuals or easily grow cosmos from seed. They come in a number of colors, including several versions of pinks and purples and white. The flower is a native of Mexico and can reach various heights depending on the mix and growing conditions. With too much water, they get a little tall and leggy. Sow cosmos after your last spring frost. Let several go to seed in fall to feed birds and provide next year’s color.

No. 2: Blanketflower

Gaillardia, or blanketflower, is an annual or a perennial in zones 3 through 11. It reseeds in our garden and lawn. This drought-tolerant beauty adds yellows, orange and rust tones to the garden. The blooms attract bees and butterflies. Blanketflowers bloom best if the gardener deadheads spent flowers, cutting the stem just above the next set of leaves down the stalk. You can also cut the plant by about one-third at the end of summer instead of regularly deadheading. If you want the flowers to reseed in your garden, leave some dried heads on the plant well into fall.

Oh no, another cosmos photo. But this one shows the contrast with the earthy colored blanketflower.

No. 3: Mexican hat

Called Mexican hat or prairie coneflower, the Ratibida columnifera is yet another member of the Aster family that reseeds easily. Mexican hats can bloom all summer long with little to no water, adding earthy colored blooms to xeric gardens. They attract bees and are considered an herb with touted use to ease stomach pain or headaches. When planted from seed, they might not bloom until the second year, but will reseed. Because the seeds need cold to help them germinate, those dropping from a plant in fall in zones 4 through 9 stand an excellent chance of becoming new plants in spring.

Mexican hat
We have different colors of blooms on our Mexican hats, from mostly yellow to more of a deep rust. As you can see, they grow right out of the rocks.

No. 4: California/Mexican gold poppy

These wildflowers in the poppy family love sun and drought, but bloom best after summer rains. We call them California poppies (Eschcholzia californica). Mexican gold poppies are a subspecies of E. californica that thrive in desert settings. Both have feathery leaves and flowers about 2 inches in diameter that resemble a cross between an oriental poppy and a tubular or cupped flower. Deadheading the remaining seedhead helps them produce more flowers, but letting the seeds develop late in summer could lead to a new stunning poppy across the yard!

No. 5: Coreopsis

Yet another member of the Aster family, coreopsis is a great self-sower. It might take over a garden in the right conditions, but our Lanceleaf Coreopsis, a classic yellow bloomer, spreads nicely in our dry climate. If you want more color, coreopsis won’t disappoint. Here, Sunset Magazine lists a dozen favorites for western gardens. Some varieties such as lanceleaf are perennials, depending on zone. They’re a fun, natural looking plant with flowers suitable for cutting.

lancelead coreopsis
Coreopsis blooms are similar to daisies. This plant has a few drying flower heads.

No. 6: Wild daisies

Like their relative the sunflower, native daisies in the Aster family can spread easily and pop up in unexpected locations. We have several that bloom in late fall and spread mostly by seed. The trick is recognizing these gems among a stand of weeds so you can let them grow to maturity and bloom, then reseed. Some wild daisies are invasive, but they’re easy to control in our dry climates. Bidens alba, also called common beggartick or Spanish needle, has tiny white flowers on lanky stems. They’re pretty and are touted to have herbal or medicinal uses, but as friends of mine pointed out, they have needle in their name for a reason. The seedheads not only help the flower spread, but get caught in nearly anything they touch, including dogs’ coats.

Spanish needles and asters

You don’t necessarily need to gather seeds from these flowers unless you want to try the plant in a different area. We’ve had mixed success with that, maybe because a particular flower tends to reseed where conditions are best for the plant.

wild daisy New Mexico
I think this is a cowpen daisy, but am not certain. At any rate, the flower prefers our ditchbank and likely wouldn’t grow as well in a more controlled garden.

If you’d like to grow some of these reseeding flowers in your garden, check with your local master gardeners or a regional garden book or blog to see which types grow best in your region without becoming invasive. Of course, I go with the premise that I can always thin volunteer flowers if they get out of hand. That usually only means smack-dab in the middle of a walkway…

Earth Day 2016: Five Green Gardening Tips

It’s Earth Day 2016! It’s hard to believe this movement started in 1970. Earth Day says “let’s get big stuff done for the planet.” I love that idea! But it’s also overwhelming. I mean, I have enough trouble taking care of myself while juggling work, family, and getting anything done to care for our four acres. But the only way to take big steps for the planet is if everyone takes a few small steps. Here are five tips for greener gardening today and all year long.

panorama of New Mexico xeric garden
If only I had a 360 camera. Mountains, sky, low-water plants, and passive solar living.

Have an empty spot to fill? Use what you have.

Sometimes a plant dies even with our best efforts, leaving an empty spot. Or maybe you’ve been studying an area of your yard all winter knowing it just needs something. Instead of buying a new plant, divide or move an existing one. Plenty of plants that spread divide and transplant easily. For example, Russian sage sends up runners that you can sometimes transplant. Our purple salvia created about five offshoots over winter, one below the garden in the grass. Tim dug up several and potted them; we even gave one to a friend. We also moved several plants. This is a great money saver (and sometimes plant saver) when areas of the garden become overgrown or one plant no longer gets the sun it should. We moved one of the three Apache plumes in our xeric garden to an area that helps screen off a little bit of our vegetable garden. Close enough to attract bees.

New Mexico rain barrel, reuse plant
Just behind the rain barrel (hint, hint) is a blue mist spirea. It did well there until we diverted some water when extending the patio (and added the barrel, which can overflow). It got too much water! So we split it up and moved it.
yarrow before moving
Yarrow is an herb, easy drought-tolerant plant and pollinator magnet.

Help beneficial insects.

Our lawn and garden attracts bees from late winter until the insects cluster tucked away in winter. The garden also attracts butterflies and hummingbirds. Moving the Apache plume, along with an offshoot yarrow and two divisions from our blue mist spirea, we just added a new hangout, inviting them to gather closer to our tomatoes and cucumbers!  We’ll add milkweed this year for the monarchs, and I can’t wait to see how that goes. We’re growing ladybugs, unintentionally. And I’m counting on them to keep aphids off the milkweed.

Annual Gaillardia plants reseed all over the garden. Bees and butterflies love them.

Avoid chemicals whenever possible.

Speaking of ladybugs and bees: insecticides kill these helpful insects along with the bad. There also is no need for chemical-laden herbicides in most cases. And I’m saying that knowing full well that half of our orchard is almost entirely covered by horehound. This member of the mint family does best in drought. I know that because if we try to hoe it up, we usually hit rock. I can’t win against a plant that grows from rocks and prefers dry conditions, especially around here. My Earth Day gift: Anyone who wants to make candy or cough syrup can come here and harvest all the horehound they want! As for care of vegetables and other plants you actually want in your landscape, paying attention to their sun exposure and watering needs helps prevent future problems. Enriching soil with compost is a slow, natural way to add nutrients. Compost tea is a gentle fertilizer.

horehound spreading
We mow and hoe, but the horehound thrives in dry conditions.

Grow food for your family or wildlife.

Growing food in the garden saves water. It sounds counterintuitive, but it’s not. I can control (within the limits of nature and horehound) the health of my edibles. And keeping them healthy can save water. Sure, they are not native to our area and require more water in the heat of summer than we could ever responsibly pour to an ornamental plant. But every tomato in the grocery store was watered, probably a with a lot more than I use. Even though water availability is regional, it also can vary. And it’s a shared, finite resource. A shrub with berries feeds birds. Fruit trees are a great example of planting a tree for shade or spring blooms with the added benefit of food. Those who don’t like the mess can choose dwarf fruit trees appropriate for their area. And no matter what anyone says, I think green bean, melon and cucumber plants are as pretty as most flowers!

This old pear tree is a stunner when it blooms. The trunk looks like it could talk.

Water responsibly, no matter where you live.

Back to water, because that is always a concern on our place and in most of the Southwest. As I said, it’s a shared and finite resource. If I use too much from our well (or from city supply), I affect the water table, the saturated, upper part of groundwater where rain has soaked through soil. Groundwater provides nearly 40 percent of water for cities and counties, and drinking water for most rural people. It’s everybody’s job to do their part in the home and garden, no matter where they live. Use of drip irrigation, watching and caring for plants sustainably, watering early in the day and using automatic timers to control sprinklers or smartphone timers to remember to turn off the hose are small but important steps every gardener can take.

Happy Earth Day!

Conserving Lawn and Garden Water: Seven Solutions

Xeriscaping isn’t for everyone; most plants native to arid zones do poorly if grown in a humid, rainy region. A plant adapted to 14 inches of rain a year will go soggy or leggy, and likely die, if it soaks up nearly 60 inches of annual rain. And vice versa. A Southwest gardener might love tropical plants, but the plants would need loads of water and attention here. Our relative humidity has dropped to the single digits lately.

xeric plants rock garden nm
Xeric plants can pop with blooms and come in many colors.

I’ve written plenty about choosing native or appropriate plants, and that’s still the most critical strategy for the combination of plant health, water savings and garden budget. Our zone 6B might have similar temperatures to zone 6B in West Virginia, but the state averages 44 inches of rainfall a year vs. 14 inches in New Mexico. If a 40 ft. x 70 ft. roof can gather more than 1,740 gallons of water from one inch of rain, imagine how many extra gallons of water fall on a plant where 40 more inches of rain fall than it’s used to receiving.

summer monsoon
We get some rain (and hail), but most of it falls during the summer monsoon season.

So, tip number one is to choose plants suitable for zone, exposure and precipitation. That’s a key to successful gardening no matter where you live.

Give in just a little to whims. If you want to indulge your love for tropical plants but you live in the arid Southwest, choose only one or two and place them in containers. Likewise, a succulent likely will survive better in the Southeast if protected from rain. You can protect it with containers that you move under shelter or indoors, or try the French solution, shown here by Debra Lee Baldwin.

Place plants with similar water needs near one another, especially if you use automatic sprinklers or drip systems in the lawn and beds. You can regulate zones or emitters, but plant roots seek water, and studies have shown that roots can even detect the sound of running water. Anyone who has had to repair pipes damaged by water-loving willow roots or the more xeric locust tree knows how this works!

drip irrigation
A low drip saves water and helps plants.

Use drip irrigation in vegetable gardens or ornamental beds. It’s the most efficient way to water. And slow drip is better for plants because the water soaks in gradually without washing away nutrients. Water containers as slowly as you can, or water half as much as each plant needs, then circle back for a second dose. It takes a little longer but avoids water (and soil nutrients) rushing out the bottom of the container. If rain in one area mostly falls during certain months, turn off or completely reprogram the sprinklers and drip controls. Or look for one that senses rainfall and shuts down watering accordingly.

Prepare soil. Healthy soil makes for a healthy plant and supports drainage. If it’s too sandy, water rushes through, and little soaks into roots. If it’s too clay-like or compacted, water pools on or just under the ground. Likewise, some plants only do well in a particular soil type. Amending soil can be tough, so choosing a plant that can handle current soil conditions is a great idea to save water and money. With healthy soil, you’re more likely to have healthy plants, and not assume one that looks bad just needs more water!

soil prep for herbs
Lots of compost enriches this soil for herbs, but the xeric area above remains as is, which is mostly rocky.

Mulch. Mulching cools roots and slows evaporation. Organic mulches eventually break down and improve soil. As with plants, it’s best to get some local advice on the best mulches for your area and conditions.

Switch to plants with purpose. Growing edible plants saves or exchanges water somewhere down the line when you don’t have to purchase the food at a store. You can fill your garden with green, but harvest herbs and vegetables at the same time. Or grow plants that double as resources for crafts, gifts and cut arrangements.

basil nasturtium

Conserving water might be more critical in the Southwest, but even gardeners in states like Alabama and West Virginia should keep water savings in mind. Local water utilities spend less in the long run when they don’t have to process as much potable drinking water, which is what most homeowners use outside. Weather patterns are unpredictable and climate disruption affects plant cycles and water availability.  Some areas receive more rain in spring and less during hot summers; taking steps to lessen the amount of irrigation needed to help plants through hot, dry periods makes for good sense and citizenship.

I realize some plants can get too much water, but that’s all the more reason to watch irrigation. And the best way to check plants and soil is to stroll through the garden, stopping to smell some flowers along the way, of course!

 

 

Get to Know Your Climate Zones Before Plant Shopping

When you shop for your lawn and garden, all nursery plants should have tags that include information about sun and water needs, and about the plant’s hardiness zone. The official zones for the United States are the USDA Plant Hardiness zones. Canada uses the Agriculture Canada Plant Hardiness Zones Map.

Improvements in Hardiness Zones

For the most part, the USDA system is based on the lowest average winter temperature. A few years ago, the USDA updated its zone map because of warming temperatures. The former map relied on data through 1986, and this one is more current. The USDA web site also has added an interactive map for users. You can enter your ZIP code and get the zone instead of guessing whether your town is light yellow or nearly light yellow on the map. So it’s now GIS-based and pretty precise; the USDA map ranges from zones 1 through 13, with 13 as the warmest zone.

USDA hardiness zones

Canada’s map is based on climate data and information about plants in the area. The formula to determine zones include mean frost period length, snow depth, high temperatures and wind data, among other information. The zones range from 0 to 9, with zone 0 as the coldest. Canada’s site also features a terrific search that gives zone-specific information for plants.

Sunset Zones a Bonus for Western States

It’s important to know whether a tree, shrub or other perennial will survive your zone’s winter before you plan or purchase; the USDA map helps with gardeners’ decisions. Sunset (Sunset Western Garden Guides) takes the information a few steps further – by telling gardeners about a plant’s chances all year long. For example, we’re in USDA zone 6B, but so are parts of Virginia and other Atlantic areas, as well as parts of Washington and Oregon. Although El Nino has disrupted normal patters, it’s safe to say that plants get lots more rain in Washington and Virginia.

Sunset looks at distance from the equator to help calculate length and severity of winters. The zone map also separates areas with similar temperature ranges according to coastal location or elevation. At more than a mile high, the elevation matters. Our days might warm as much as a comparable location at 2,000 feet altitude, but our nights cool considerably more. Most of all, Sunset knows the western part of the country. Sunset has 24 zones for the American West, divided by geography and climate. Our small town isn’t notated on the map, so it’s a little tough to determine our exact zone. But Sunset places us in the high desert/intermountain region, and the information still is helpful.

Interestingly, Sunset also provides zone information for the rest of the country. It would be well worth it for gardeners east of the Rocky Mountains to review the Sunset zones for information such as wind and climate extremes.

Gardeners can avoid confusion about zones in plant purchasing and care information by knowing both USDA and Sunset numbers for their locale. Typically, all plants except Sunset’s own will use the USDA zone on the tag.

Use Zone Data with Microclimates

If you’re still uncertain about zone, you can check with local Master Gardeners. Another reason to ask a seasoned gardener about climate and zone is microclimates. In many Western states, zone varies within a metropolitan area. Think of the areas above and below southern California’s thermal belts. The ocean has little to do with the climate in those distinct areas. In Albuquerque, temperature and wind can vary markedly from the foothills of the Sandia Mountains to the valley floors.

Knowing particulars for your area of a town or region helps, but you can take it a step further if you want to push the edges of a plant’s hardiness zone or care needs. If you’re half a zone colder than the plant’s care information recommends, plant it against a south-facing wall. Plants that need protection from heat can go on the northeast side of your home, where the house shades them on blazing afternoons.

And since we’re all about the water out here, microclimates help with water use as well. For example, I might be able to place a shrub that needs a little more water at the bottom of a hill, welling on the downside to catch some of the rainwater.

So remember to pay attention to zone, sun and water needs when buying plants, especially in chain stores, which might stock plants too far out of your zone to keep alive all year. Your plants will be healthier and you’ll save money and time.

Plant Select 2016: Waterwise Grass and Groundcovers

I get so excited when I see the Plant Select press release in my messages each spring. I love any new plant introduction or award winner, but Plant Select focuses on plants that adapt to – and thrive in – the dry, wild conditions of the intermountain regions and high plains. Gardeners can be confident that their selections will work in much of New Mexico, Arizona, Colorado and other western states. This year, Plant Select announced two new groundcovers, and selected a drought-tolerant turf and groundcover. Anyone ready to switch out a high-water lawn should take note of these choices:

new ice plant orange flowers

Red Mountain Flame ice plant (Delosperma ‘PWWG02S’). An ice plant with deep orange to red flowers! Ice plants came to the U.S. from South Africa. The plants use little to moderate water once established, yet they provide gorgeous, evergreen groundcover for the xeric garden. One reason is that they spread quickly. But ice plants won’t get invasive. When ours have spread too far, we’ve even transplanted some of the extra plant to another area of the garden with success. They’re usually yellow or pale pink to purple. I’m thrilled to have a new ice plant color choice for rock gardens and other beds. It’s also perfect that New Mexico’s own David Salman of Waterwise Gardening produced the Red Mountain Flame seedlings. Grow ice plant in zones 4 through 9. Red Mountain Flame needs a mix of sun and shade.

Alan's Apricot ice plant
Alan’s Apricot ice plant boasts larger, color-changing blooms. Image courtesy of Plant Select and Alan Tower.

Alan’s Apricot ice plant (Delosperma ‘Alan’s Apricot’PPAF). The apricot-colored blooms of this new introduction are similar in color to existing ice plants, but larger. It also changes color to a pinker hue and then back again. Ice plants turn heads in summer when they fill with blooms on the low foliage. I can only imagine how Alan’s Apricot’s two-inch blooms will look in mid-summer. The larger, showy flowers also will shine in a container or the landscape as blooms begin to open or close each season. The ice plant was developed by Alan Tower of Spokane, Wash. Also for zones 4 through 9, a variety of soils, and a mix of sun and shade.

Moroccan pincushion

Moroccan pinchusion flower (Pterocephalus depressus). The Moroccan pincushion has similar foliage and an inch or so more height than ice plants. The pincushion flowers are light pink to rose in color and leave silvery seed heads after fading. It’s also evergreen, offering winter foliage in zones 4 through 8. Add Moroccan pincushion to a rock garden, raised bed or large container in full sun. The plant needs little to no water once established and should have soil that drains well.

dog tuff grass
Dogs can run on and water drought-tolerant DOG TUFF without damaging the grass. Image from Plant Select and Kelly Grummons.

DOG TUFF grass (Cynodon ‘PWIN04S’).  Why have no lawn at all when you can have areas of turf for kids and pets, along with the look and cooling effects of grass? I’m all for removing some lawn, even more if you have a high-water grass. But I’ll never stop trying to convince people to leave a little grass. DOG TUFF lets homeowners have the best of both worlds: saving water and keeping a lawn. DOG TUFF has an extra quality that might have influenced Plant Select’s choice. Like the name says, it’s tough, holding up to foot traffic even in a xeric lawn. It also holds up to your dog’s help with “watering.” The grass comes in plugs for easier spread and planting. DOG TUFF needs more water the first year, but once established, the warm season grass should return in late spring for all-summer coverage in zones 5 through 10. Learn more about planting and caring for DOG TUFF here.

Plant Select is located in Ft. Collins, Colo., where its staff puts plants to work in test gardens to see how they do with little water. Plant Select also evaluates plants for adaptability, durability and ease of care. They also consider how attractive the plant is in the garden and whether it’s wildlife friendly.

Add Evergreens to Your Low-water Garden Plan

Most of my gardening friends have started seeds and marked up pages in catalogs because when spring is in the air, we get excited, even impatient, to return to the garden. It’s easy to plan for spring and summer bloomers, but also helpful to think ahead to next winter, when blooms fade.

snow on evergreens
Winter can be pretty in any garden, and snow on evergreens… gorgeous.

Evergreen shrubs and trees add visual interest, homes for birds or other wildlife and privacy in winter. Evergreens are particularly helpful in dry or cold climates. Choosing an evergreen for the low-water landscape does not confine the gardener to conifers. There are many choices to fit nearly any xeric garden design or location, such as santolina.

santolina
Gray santolina is evergreen — or evergray — and produces bright yellow flowers in summer.

Saltbush (Atriplex canescens) Saltbush, also called four-wing saltbush, is a native plant of Western states. Although its colors aren’t bright or striking, saltbush is an unusual and interesting plant. Native Americans once used the stems for fuel and made yellow dye from the plant’s leaves. Although I haven’t tried the seeds, they are edible, and we once saw locals gathering the seeds when driving south of Albuquerque. When the seeds emerge, they make a gorgeous contrast to the foliage, which is more silvery green. And they’re swirly and paper-fine to the touch. Saltbush is native to alkaline soils and salty high deserts.

four wing saltbush
The four-wing saltbush is a native that looks terrific in a natural landscape.

Boxwood (Buxus). Boxwood is surprisingly drought tolerant if given some shade or in a northern exposure, deer resistant and easy to care for in the lawn. In fact, the plant is subject to fungal disease, but when panted with the crown about an inch higher than its position above the soil in its nursery pot. Well-draining, slightly alkaline soil also helps, which makes it a perfect evergreen shrub for most of New Mexico. Most boxwoods grow in zones 5 through 9.

Although boxwoods don’t need substantial attention or trimming, gardeners who enjoy pruning will love shaping these plants to match the landscape. A new boxwood from Monrovia, Petite Pillar Dwarf Boxwood, has a naturally column-like form, which sets up easy maintenance for the gardener. It fits perfectly in containers, but requires regular watering, especially in heat.

agaves mass planting
Agaves surround this tree at Tucson’s Desert Botanical Garden.

Succulents. If they’re hardy in your zone, succulents can provide year-round interest, especially in xeric gardens or along walkways or fences. Their shape adds a unique look to winter gardens. For example, the agave (Agavaceae) is like garden art with its upright, sometimes symmetrical design. The plants are long-living perennials, and some varieties are hardy down to zone 5. With about 300 species to choose from, gardeners are sure to find one that suits their design and zone. Although they grow slowly compared with shrubs, agaves need a little room to expand. Set off the plant’s color with a contrasting ground cover such as speedwell or purple iceplant for more summer color.

blue agave
These blue agaves (Agave parryi, or Parry’s agave) add texture and color to our winter garden.

The aloe vera provides a similar look, although the leaves are fleshier and more upright. The plant is not as cold hardy as agave, and needs to be outside only in climates with warm winters, no lower than 40 degrees at night.  Aloes also add value to your garden. We’ve used aloe directly from a plant to soothe sunburns.

Yuccas also are easy to grow, and their slimmer, spear-like leaves look brilliant all year long. They’re also a diverse xeric plant; you can choose a variety that’s bushy and full at the bottom or more open and fanned out.  Check the variety’s mature height when purchasing to make sure it won’t get too tall for the location you choose. Some varieties, such as Joshua Tree, grow to 15 to 20 feet high. After a few years, yuccas produce summer flowers on tall stalks from the plant’s center.

Caring for these succulents is simple. They need some sun, but can burn if exposed to too much direct sunlight. And the only problems with the plants typically come from overwatering. Avoid watering these succulents in winter, or the plant can get root rot.

Conifers. Piñon pines (Pinus edulis and a few others) are native to New Mexico and Arizona. It’s more like a rambling, tall shrub than a tree, easy to care for and used to semi-arid regions. The seeds, or nuts, are edible.  Icee Blue Yellow-wood (Podocarpus elongates ‘Monmal’) has stunning blue foliage in winter, but only in southern climates (zones 9 through 11). It has a thin, conical shape when mature and can be trimmed into classic Christmas tree shape, a nice touch for a warm winter garden. As with all xeric plants, Icee Blue needs a little extra water until established, then gardeners can cut back. Alligator juniper is a terrific bird shelter that has interesting bark along with evergreen branches.

Icee blue also is the name given to a spreading juniper (Juniperis horizontalis ‘Icee Blue’). I’m not a big fan of juniper, mostly because of allergies. But the plant can provide evergreen groundcover in a low-water lawn. Icee Blue is hardy down to zone 2, and prefers full sun. If controlled with trimming or planted in mass plantings, junipers are a low-water alternative to shrubs and other groundcovers. If you want to cover an area of ground quickly with a plant that requires little maintenance or water once established, check with your local nursery for a juniper that can survive your winter lows.

New Mexico — One of the 50

As I long for spring to return so we can get back to our gardens, I begin to fantasize about living in Maui or Tucson, Ariz., or anyplace warmer. But today, I’m reflecting on the beautiful state in which we live. And I thought it was time to dispel a few myths about New Mexico, especially for people who live far from the state and have not (yet) visited.

From the top of a ski run at Angel Fire Ski Resort in northern New Mexico, you can see all the way to Eagle Next Lake and the peaks near Taos.

First of all, New Mexico Is a State!

Nearly everyone in our state who travels, stays active in social media or makes online purchases has encountered the phenomenon. I’ve had questions about shipments being international, and New Mexico Magazine runs a terrific column featuring some of the stories from N.M. residents about this confusion.

I know we don’t have a large population, but it hurts to see a map with Arizona and Texas labeled and the empty space between (or the AZ label on our bootheel-shaped state). New Mexico became a state in January 1912. We were the 47th state to join the Union. According to the N.M. Genealogical Society, achieving statehood took some time “in part, by a general ignorance about the territory and suspicions toward its people.”

We still have cowboys here, but New Mexico offers much more.
We still have cowboys here, but New Mexico offers much more.

Some things haven’t changed, I guess. It is true that our state was once part of the Mexican Republic, but that only lasted about 25 years during the 1800s. Our state boasts more than “cowboys and Indians” for our history. Ancient history includes Folsom Man, Clovis Man and the Anasazi.

It Snows in New Mexico

Maybe because of our close proximity to warm and sunny Mexico and the low deserts of Arizona, the perception of New Mexico as a hot, dry desert prevails. It’s partially correct – our climate is extremely dry, and it gets hot in many areas of the state in summer. Climate and gardening zone are affected by more than latitude. New Mexico is on the U.S. southern border, but the Rocky Mountains run through our state, as does the Continental Divide.

Albuquerque, our largest city, is at the same altitude as Denver. Our place, which I consider as intermountain or high desert, stands at 6,300 feet in altitude, and we’re surrounded by Lincoln National Forest. The Sacramento range is just southwest of us. Sierra Blanca, the peak that hosts Ruidoso’s Apache Ski Area is at just over 12,000 feet high.

This year, we got 18 inches of snow just from Winter Storm Goliath, and areas of the state measured their snow in feet. In northern New Mexico, the average annual snowfall has averaged more than 150 inches in Red River.  Even Albuquerque receives 9 to 10 inches of snow a year. Having said that, some southern areas of the state easily average more than 100 degrees in summer and have palm trees lining many streets.

The sun usually comes out and melts our snow quickly. It took longer to melt the snow from Goliath.

Gardeners Grow More than Cacti

The desert assumption includes our native and garden plants. A major purpose of this blog is to show gardeners in Southwestern and Western states that native and xeric gardens can be gorgeous and save water, and that gardeners can grow other than succulents.

Our rain typically comes as monsoons beginning in early July.

I’m not saying that N.M. gardeners avoid cacti and succulents when choosing plants for their garden or home, but so much more grows here. Depending on the region, gardeners hybrid and native roses, aspen trees, herbs and plenty of flowering perennial bushes and annual flowers. No area of our state escapes drought regularly and our average annual precipitation is lower than much of the country. So we just have to garden selectively and responsibly. Many species claimed as invasive in other areas don’t spread so rampantly here, and vice versa.

I’ve grown so accustomed to xeric and rock gardens that I’m a little turned off by lush, formal looks. Xeric gardening is most effective and pleasing when gardeners work with the natural terrain and climate. Use of native plants, rocks and succulents can combine for a perfect palette.

Southwest Gardening Can Be Challenging

Our gardens and natural areas look amazing throughout the year, but gardeners who transplant from warmer, and especially wetter, climates find themselves going through an adjustment period. It’s more likely many of our native and xeric plants will die from too much water than not enough. Once gardeners learn how to ensure the soil is prepped and that they water a little extra only until a plant gets established, they’re likely to have more success than failure in the garden.

One of the reasons it’s particularly difficult to garden in parts of New Mexico is the weather extremes. In the high desert, days can become warm, and the sun intense. But at night, the desert cools considerably. Daily temperature extremes of 40-plus degrees from dawn to evening are not uncommon here. Add gusty dry winds to the mix and any plant but a native to the area might struggle a little. The state’s geographic diversity also means that conditions vary considerably around the state. USDA zones range from 4 to 8 around the state. Colorado’s zones are cooler than ours, and Arizona and West Texas are warmer on average.

New Mexico Is Enchanting

New Mexico’s state nickname is “Land of Enchantment” and it fits the bill. With mountains and plains, we have gorgeous views in most of the state. Sandia Crest in Albuquerque is so named because of the beautiful watermelon color the mountains take on at sunset. We have forests and rivers, along with dry river beds. It can green up here in summer, but if you’re used to all-green landscapes, you’ll either be disappointed or truly amazed.

Diversity of people and wildlife also make New Mexico an enchanting state. Every quadrant of the state has Native American reservations and history. More than 2 million residents were counted in the 2014 census, and nearly half are Hispanic or Latino.

Our mountains are home to black bears, deer and elk. And our plains are home to antelope and roadrunners. We’ve got ranches, oil fields and farms. Nut production is high here for some varieties. Dormant volcanoes, lava flows and white sands dot the landscape.

It's tough to beat our enchanting, colorful sunsets and sunrises.

New Mexico is far from perfect socioeconomically, but well worth the visit. You’re sure to be enchanted.

Five Fun Annuals for the Low-water Garden

It’s more waterwise – and less expensive – to grow perennials. When a plant’s getting started, it needs a little more water. So once a xeric perennial plant has become established, the gardener should not have to add much, or any, water.

cosmos in rock garden
Low-water gardens can combine lots of perennials with bits of annuals. Cosmos re-seed easily from year to year in our zone 6B low-water garden.

By nature annuals last only one year; you’ll have to water seeds or transplants a little more than you will an established perennial. Having mostly perennials in your garden is a waterwise and cost-effective strategy, but most gardeners want to add a little color or variety to their gardens. Enter the annual flower.

You can save money by purchasing annuals as seeds or by selecting native varieties that will likely re-seed in your garden next year. And save water by mulching annual beds after seedlings are large enough. Plastic cups or leftover nursery pots make great “protectors” while laying mulch. Just place cups large enough to avoid bending or breaking the plants upside down on each seedling in the bed, or a portion of the bed, before carefully pouring in your mulch. Then lift the cups and adjust mulch around the plants.

Native annuals also should use less water than “splurge” plants, but you won’t do a ton of damage to your water-wise efforts with a small container of your favorite annual.

Here are some of my favorite annuals, particularly for low-water gardening in zones 6 and 7.

zinnias annuals
A bunch of zinnias adds easy and vivid color to any annual bed.

Zinnias. Without a doubt, zinnias are a favorite annual. They’re simple to grow from seed; in fact, zinnias don’t transplant well, although it can be done if you start seedlings in peat pots. This way, you can transplant the peat pot with the seedling when the weather warms. The hardy flower requires sunshine and soil that drains well. Add a little organic matter to the container or bed to ensure drainage. Deadheading spent blooms keeps flowers coming and helps keep the plant from getting tall and leggy. Besides, the bright orange, red or coral flowers are terrific for arrangements. Check your seed package for flower type, size and plant height when selecting zinnias for annual containers or beds.

California poppy. The California poppy (Eschscholzia californica) is a perennial in warm climates and a frequent re-seeder in moderate zones. The wispy, fern-like foliage has a silvery-gray color, and thin stalks support orange and yellow blooms that resemble a flatter, simpler poppy. Deadheading the flowers is a little bit of work, but well worth the effort. The California poppy technically is an herb, but the plant is poisonous if eaten. It’s a terrific pollinator.

california poppies
These poppies love sun and heat. Spent blooms are easy to spot for deadheading; the petals drop and leave a long seedhead.

Cosmos. A relative of the aster, the cosmos is a varied and versatile flower with nearly 20 species. Just give the flowers lots of sun and avoid overwatering or overfertilizing; too much shade and water can make them lanky. I love cosmos at the back of a bed, but they come in various heights. The flowers easily re-seed, so be sure you like them before planting. Birds land on cosmos plants left in our garden and peck at the seeds all winter.

Cosmos plants can look a little wild, but the flowers normally form a perfect shape. Our grape tomatoes grew into the wild cosmos.

Portulaca. The portulaca family includes purslane, which can be an invasive, water-sucking weed. Still, some people enjoy the edible qualities of purslane. I prefer Portulaca grandiflora, also known as moss rose. The tiny flowers’ foliage resembles rosemary leaves, and the flowers make an excellent groundcover, spreading throughout the summer. They also work well in containers. Space them out, and they’ll quickly fill the container and drape over the edge. Instead of cutting spent flowers, you simply need to pinch off the dried-up bloom to encourage more color. One caution: portulaca seeds are tiny, and can spread or hide easily in soil. Plant something else in the same container next year, and you’re likely to have a pretty little portulaca pop up.

Tiny portulaca flowers pack a lot of character.

Sunflowers. Who can resist a stunning photo of a field of sunflowers? The Helianthus annus takes a little more water, but can tolerate brief periods of drought. Between their water needs and propensity to get munched by deer, they’re not the perfect annual for our garden. Having said that, we always try to get a few sunflowers going, especially the crimson-colored varieties. Many of our thriving sunflowers come up as volunteers, likely thanks to area birds. Sunflowers make perfect pollinators; bees can’t get enough of them. And those that survive deer provide seed for birds in fall. Maybe it’s because I’m so tired of winter, but I can’t wait to see these signs of summer springing up around our property!

10 Reminders for Waterwise Gardening

Although the drought has eased in New Mexico and some areas of the Southwest, it’s still serious in many regions. Plus, there are plenty of reasons to save water in the yard, garden or farm all year long, regardless of your region’s current drought status.

No matter where you live, the foremost reason to adhere to low-water gardening designs and principles is to conserve water, which is the right thing to do for this and future generations. I doubt homeowners in California, many of whom typically enjoy steady rainfall of 18 or more inches a year, were concerned about drought when they had their yards designed decades ago. In fact, the 1913 completion of the Los Angeles Aqueduct likely marked the beginning of the phenomenon that occurs when too many residents are concentrated in a geographic area, especially one not conducive to urbanization.

The aqueduct and population are only part of the problem in California or in any region short on water. The Environmental Protection Agency estimates that every American uses about 320 gallons of water a day. Nearly 30 percent of home use flows outdoors, including on lawns. All-told, home landscape irrigation accounts for some 9 billion gallons of water a day around the country.

If you’ve read past blog posts, you know that I plead for a measured and appropriate response, one that if taken before severe drought strikes can prevent community, and eventually global, water crises. That approach includes native or xeric landscape design, not the destruction of all living plant material in a lawn. As I’ve said before, replacing grass with gravel doesn’t necessarily save water or energy.

Our native grass (and weed) lawn receives no water except rain.

For a 2015 recap and 2016 garden prep reminder, here are the 10 easiest ways to save water in your lawn and garden:

1. Convert some turf to gravel if you like, using oasis zones and smart xeriscape design principles. Involve a landscaping professional if the job is big or the concept overwhelms you.

2. Convert high-water turf to a native, low-water grass. The best choices for high desert areas are Blue grama (Boutleoua gracilis) and Buffalo grass (Buchloë dactyloides). A new hybrid called Dog Tuff (Cynodon hybrid) also comes in plugs for quicker spread.

3. Water wisely, cutting back in winter and irrigating only in the cool of the morning during summer. Use drip irrigation instead of spray or sprinklers when possible. Add mulch around plant beds.

Drip irrigation saves water and improves plant health for edibles or ornamentals.

4. Look for signs of water waste, such as runoff. Create a dry-river bed, bioswale or terrace to capture water and place plants with higher water needs in swales or at the bottom of inclines. Well around plants that need a little more water.

5. Remember that even low-water or xeric plants need extra water the first year; if the plant doesn’t make it because it dries out, you’ve wasted whatever water you used to irrigate plus the cost of the plant.

6. Choose perennials over annuals. Every time you plant annuals, you must water them extra to help them get established for the season. Growing more perennials and letting native annuals and wildflowers go to seed is a better strategy; leave one small bed or container arrangement only for annuals each year.

7. Grow edibles in your lawn or landscape. If you don’t want the look of a full-blown kitchen garden from the curb, place perennial herbs or low-water plants with berries for your family or birds in the most visible areas of the landscape.

8. Make smart use of containers and raised beds. Containers and raised beds use less water than the ground. Just be careful to water slowly. If water pours out the bottom of the pot, you’ve probably given more than the plant needs, and if you water rapidly, you can wash nutrients from the pot’s soil mix.

9. Check and improve the soil. It’s easy to ensure good soil and drainage in containers, but less so in the lawn. Even without a soil test, a gardener can see when the ground around a plant doesn’t drain well; that can be the death of many xeric plants. Adding organic matter and loosening the soil (but not tilling) can help build soil health over time.

10. Capture and use rain water. If you don’t want to water edibles this way, at least catch rain from your roof to water your ornamentals. It might seem like one 50-gallon barrel isn’t enough, but as with all waterwise gardening, every little bit helps.

Deer graze the native grass that receives only nature's water, and a rain barrel provides water for containers.

Five Favorite Cold-Hardy, Low-Water Perennials

With winter in full swing, I’m amazed at the hardiness of some of our low-water plants. Anyone who lives in a northern or high-altitude zone who’s planning to add or replace some plants this spring with low-water alternatives should feel plenty comfortable with the number and variety of choices. Planting perennials saves you money – and water. Xeric perennials only need a boost of water the first year or so, and then can often make it with no irrigation. Here are a few of my favorites by category:

This purple iceplant had a few blooms into fall; we’ve had them covered with blooms in summer.

Ground Cover

The iceplant (Delosperma) is a sun-loving groundcover that spreads rapidly and rewards gardeners with bright pinkish-purple (D. cooperi) or yellow (D. congestum or D. nubigenum) flowers. We thought it would be too cold here in zone 6B, but our purple iceplant thrives on the northeast side of our home. It’s a stunner, especially in rock gardens, where it can cascade slightly over rocks or borders. It’s also an easy groundcover to transplant. Other low-water cold-hardy groundcovers are several sedums, such as Dragon’s blood (Sedum spurium), and low-growing sages (Artemesia filifolia or A. frigida).

Dragon’s blood sedum has such a rich, red color. It’s a cold-hardy perennial groundcover perfect for xeric rock gardens.

Flowering Perennial

Red hot pokers (Kniphofia uvaria) are workhorses in low-water, cold-hardy gardens. Also called torch lily, the plans resemble a lily in its foliage. But the tall, torch-shaped blooms with red and yellow tubular flowers can last for weeks. Hummingbirds visit the flowers, and birds often visit spent blooms. Meanwhile, the plants form clumps in the ground that spread. Many gardeners use them as fence borders, and they’re one of the easiest cold-hardy perennials to care for in a low-water garden. Other low-water, cold-hardy flowering perennials are Dusty Miller and Gayfeather, to name a few.

Deciduous Shrub

The Utah serviceberry (Amelachier utahensis), also called a shadberry, is a low-water shrub that drops its leaves in winter but only after turning several gorgeous colors and producing berries for birds and other wildlife. It is closely related to the Western serviceberry (A. alnefolia). It’s native to low-mountain or high-desert areas of Utah, New Mexico and along most of the Rocky Mountain region. We purchased a stock of bare-root serviceberries that we’re raising in a protected area near the river so they need less water while getting established. Other low-water deciduous shrubs cold-hardy in high deserts or intermountain regions are the Leadplant, Fernbush and Sumacs.

Evergreen Shrub

Mahogany (Cercocarpus) uses very little water and has an interesting, desert-like look in the landscape. The evergreen shrub can adapt to temperature extremes up to 100 degrees F, and is cold hardy to 20 degrees below or more, depending on the type. Curl-leaf mountain mahogany (C. ledifolius) can get large if left untrimmed, but the little-leaf variety only grows to about 8 feet tall. Both do best in full sun and with little water. Other cold-hardy evergreen shrubs that work well at high altitude are Damianita and Cotoneaster.

Tree

The alligator juniper (Juniperis deppeana) is one of few junipers that I really love. That’s because I’m allergic to juniper pollen, as are many people who must live around the plants in areas where the air is plenty dry. Junipers thrive in poor soil and low water conditions and they’re long-lasting evergreen trees and shrubs. The alligator juniper is named for its reptilian-like trunk, making it more interesting in the landscape. Many also have multiple trunks. Alligator junipers do well in elevations between 4,500 and 8,000 feet. Lots of other low-water trees fare well in cold climates, including the Netleaf Hackberry, Mexican Elder and Gray Oak.
