When water is as scarce as it always seems to be in New Mexico, especially this year, I appreciate all of the native and drought-tolerant plants that hang in there until rains finally arrive. After all, it’s the smart and right thing to do here in the Southwest: grow plants that need little to no watering from our wells and taps.
And we follow those principles, doing what we can to save water. Still, I love some plants too much to give them up completely, and I imagine that’s true of many people who move to our dry state. I would hate for any gardener to feel badly for having a few guilty pleasures from the plant world. Here are some strategies for finding the middle ground between gardening sustainably and growing plants you love.
Plant high-water users only as occasional fillers and in moderation. By high-water plant, I mean not xeric, or needing some supplemental watering. If a plant doesn’t meet the soil, sun exposure and watering requirements, you’re unlikely to have much success and will have to resort to photographs from botanical gardens!
Fill in color with a few annuals. I fill a few patio containers each year with an annual or two or pop a few annuals between xeric plants that flower for only part of the season.
Grow a few houseplants you love. Geraniums are a favorite of mine, and I don’t have to give them much water in the winter while they survive inside near a sunny window. My new guilty pleasure is violets, although they stay inside all year. Growing orchids, violets and other houseplants more suited to tropical climates can be a guilty pleasure without adding much to water usage. Of course, that’s assuming you stick to a few plants only … if you can.
Create conditions that help the plant survive with less water. Use mulch, shading or other exposure strategies and careful timing with monsoon rain to help a nonxeric plant make it through hot, dry periods. And accept that your plant might not bloom as much as it would in a wetter climate by enjoying the blooms you get.
Choose plants you love that are useful to “waste” less water. If you’re growing food for your family (and not wasting lots of harvest), you’re replacing some of the water that might have been used to grow the same food on a large farm, and doing so locally. Plus, the benefits outweigh a little bump in water use and cost. Or grow some cut flowers you love instead of buying them in a store for your home or family and friends. Finally, some flowering plants that require a little more water provide food for hummingbirds, bees and butterflies. Although natives are better, adding a few flowering plants not native to your area can help pollinators.
And finally — use rain barrels to water your lovelies during dry weeks.
Xeric plants are smart, easy-care choices simply because they need little watering once established. Still, I’m sure some people avoid trying new plants, or opt for mostly gravel, to lessen time needed caring for ornamental plants.
I’ve got five great options for Southwest gardeners, each hardy in our zone 6B garden and during summer heat. Although all are not technically xeric, they can thrive with little to no watering other than rain. Mostly, these plants need very little care, so try something new this year!
Yarrow (Achillea sp). Yarrow is an herb, and a close relative of chamomile. Yarrow is said to aid digestion or heal wounds when applied as a pulp. Take a look at the scientific name (ever heard of Achilles and his heel?) and you can see how many years people have used yarrow for medicinal purposes. Achilles is said to have applied yarrow tinctures to heal and prevent wounds.
I grow yarrow because it’s pretty, attracts pollinators, and is one of the easiest perennials to maintain. Technically, yarrow needs a little more water than other low-water plants when summer temperatures hover at 90 degrees and higher, but our plants have made it through many seasons with one spring watering and natural rain after that. They’re hardy in zones 5 through 8. You can cut the spent blooms off to encourage more flowering. But for easy care, leave them on the plant, especially in cooler regions. or cut them back all at once for a second bloom in warmer climates. When trimming, you’ll probably see some tiny flowers close to the leaves that should shoot up and open. We’ve transplanted several yarrow plants with no trouble.
In windy areas, ornamental grasses stun in the garden. We often place them as single plants in a grouping of others, but I love the look of a row or grouping of the same grass in the landscape. Even those that aren’t native tend to need less water than some plants, since they don’t truly flower, but can produce lovely stalks topped with seeds. And you can mix textures, colors and heights for landscape interest. There are so many choices!
Even those grasses that aren’t native need little care and use little water. A few (like Silky threadgrass) can spread, but you only need to pull or dig up the tiny starts in early spring to control where they grow. We like to add one annual such as Purple Fountain Grass (Pennisetum secateum ‘Rubrum’) each year for color pop, but our other grasses make it through winter.
Just check to see average zones. For example, the Purple Fountain Grass can overwinter in zones 8 through 11. And ask whether your favorite is a warm-season or cool-season grass; that helps you know when to plant it and whether it will survive winter or need a little shade in the heat of summer. All you have to do is shear back the foliage each spring as the grass begins to green at the base. So, so easy.
Prairie or desert zinnia (Zinnia grandiflora), is an easy and attractive groundcover with sunny yellow flowers that grows in zones 4 through 9. The plant is native to New Mexico, Arizona and parts of southern Colorado, so it’s hardy in Southwestern soils and survives drought. Ours were already in our garden, and I have heard that the plant can be a little challenging to get started. My guess is excited gardeners plant the zinnias too soon, before soils have warmed. Ours cascade down a rock wall, coming up each year in little soil, but plenty of warmth from the rocks. The rocky soil also drains well, which likely helps keep the plants healthy and spreading at just the right rate (not invasive). The foliage browns in winter, but is so small it doesn’t look messy. All I do each year is put on my gloves and gently pull away the dead foliage when I see it greening up at the bottom. Once you do that, the plants get the sun they need and begin growing and flowering.
Gopher spurges (Euphorbia rigida) are among few plants that handle extreme cold (down to -20 degrees) and the high heat of zone 11. The plant is called gopher spurge because it has been said to repeal gophers, but I’m not sure there is any proof of that, or anything at all that truly repels the underground destroyers. I can say that ours have survived, save some deer chomping. The stalks that were eaten succumbed to cold, but I just cut them off at the base of the plant.
Otherwise, our gopher spurge has grown nearly a foot in one year and was among the earliest flowering plants in our spring garden. We also have a Euphorbia ‘Ascot Rainbow’ we bought locally last year, and the foliage alone is beautiful. This newer plant also has survived winter and is beginning to bud out. All you have to do is cut off stems after the seeds ripen; new stalks will come up and you can enjoy the silver-green or colorful rainbow foliage all year. Gopher spurge and many other Euphorbias are succulents, so they’re lovers of sun, heat and low water.
It’s the year of the Coreopsis! And I’m so glad. The native flowering plant is so versatile. It looks beautiful in rock gardens or more formal landscapes. Just place coreopsis in well-draining soil and most perennial varieties should be hardy from zones 4 through 9. Sometimes called tickseed, coreopsis comes in several varieties and deer seem to ignore the plants. Because the native plants tend to come up along ditch banks or other disturbed areas they tend to easily grow in any Southwest garden conditions. The bright yellow blooms of Lanceleaf and Grandiflora coreopsis are common, and breeders have grown new varieties of Coreopsis with color variations.
Deadheading flowers as they dry up will keep them blooming, but if you find deadheading takes too much time, wait until a good flush of blooms has begun to die back and shear the flower stalks off all at once; you should get more blooms.
The new year is almost upon us, but gardeners don’t have to wait until spring to dream, plan and even shop for new plants.
You can take some time in winter to plan your garden. Doing so usually cheers my mood and makes me feel like I’m getting something done, even if I can’t do much outside. Here are a few tips for Southwest gardeners for winter planning and shopping.
Check Out New Plant Introductions
Each year, breeders offer new plants adaptable to conditions or resistant to diseases. Many independent testing organizations and growers conduct trials to see how plants fare in harsh conditions such as heat or drought. A favorite regional source is Plant Select in Colorado. The nonprofit organization tests and creates plants for the Rocky Mountains. You can search or browse their plant selections for zone, soil type, sun exposure, water needs and other characteristics. A new 2017 selection is the Sungari redbead cotoneaster (Cotoneaster racemiflorus var. soongoricus). The shrub is a hardy plant and fall stunner in a xeriscape.
All-America Selections also releases trial information on ornamental plants and vegetables each year. Although some of the plants are not suited for New Mexico gardens, AAS includes regional winners for the Mountain/Southwest region. For example, its 2018 winners include Mexican Sunrise Hungarian Pepper F1. This past summer, I sowed 2017 national winner Dianthus Interspecific Supra Pink F1 seeds in a garden bed and the plant bloomed well into fall. You can find AAS winners at retailers that carry national brands such as Bonnie and Burpee plants or seeds (Johnny’s selected Seeds or Territorial Seed Company).
Regional growers and local nurseries often carry new plant introductions. Typically, you can learn about new plants by subscribing to the company’s newsletter or by following them on social media. High Country Gardens (whose chief horticulturalist, David Salman, is from New Mexico) recently released a list of new plants the company offers in 2018.
Finally, the Sunset Western Garden Collection is designed specifically for Western gardeners. Sunset lists a collection of waterwise plants, but you might have to do some research to find out where to buy the plants you spot there.
Order and Review Seed Catalogs
Growing plants from seed takes a little more work, but can save you money. And some plants do better grown directly in the ground (cucumbers and squash come to mind). Even though you’ll have more success and save water by growing plants suited to your region, it’s fun to shop for rare or unusual annuals for containers or other special spots in your garden. It’s much less expensive to buy seeds for plants that probably won’t make it through the winter.
Most seed companies ship catalogs for free to anyone who requests them and I’ve been receiving mine since before the holidays. In addition, you can find online versions of most seed catalogs. Flipping through catalogs can give you great ideas about new or unusual plants or even inspire where to plant them or ideas for companion plants for a particular flower or shrub.
Read and Research
Catalogs are one source of plant ideas, but local and regional gardening books and blogs should be your go-to sources. Combining information on plants featured in your favorite gardening books with catalogs and new introductions can help you begin planning and shopping.
In your research, look for ideas such as drought-tolerant plants for easy care, plants for birds and pollinators, or colors and textures you long to add to your garden. Think about herbs and vegetables your family loves and see if you can grow a variety within your space or time constraints. And always read books and websites with a critical eye for credible information and plants most likely to grow in your zone, soil type, sun exposure or water availability.
If you don’t have a good gardening book specific to your state or zone, find out if your local master gardeners have published a plant or gardening guide. And check out my Resources page for books and links on gardening in New Mexico, xeric gardening and other topics.
Shop Locally and Online
Some gardeners prefer to touch and see plants in person, at least to decide on colors or shapes they like. Just beware that some chain stores offer plants each year that aren’t suited to your region or at least offer fewer plants tested for Southwest and xeric gardens. For example, no retailers in New Mexico offer Plant Select products, but High Country Gardens sells Plant Select through its catalog and online store. Shopping, or at least researching, online also can save time. Many online catalogs have search filters. You might be able to search by plant name, bloom color, bloom time or average temperatures and rainfall.
Many online nurseries let you order now and then ship your plants at the best possible time in spring for your zone. So, there’s really no reason you can’t get a head start. Happy plant shopping!
Help your garden grow and even help local farmers by including native plants that attract bees and other pollinators to your yard.
Diseases such as Colony Collapse Disorder, and other factors, have led to declining domesticated bee numbers in the United States. However, there are plenty of species of wild, or native, bees still buzzing around looking for pollen.
Wild bees typically aren’t part of hives; they fend for themselves, living in the ground or in hollow stems of plants. Pesticides, insecticides and other dangers still can harm wild bees. Recent studies have shown that newer insecticides called neonicotinoids are absorbed by plants and can show up in pollen. Farmers and home or business owners use neonicotinoids widely to stop pests. They’re toxic to domestic and wild bees. Avoiding use of insecticides that also harm bees is one way to help bees survive and thrive in your landscape.
Here are a few other easy steps to take:
Since wild bees nest in soil and hollow branches, homeowners can ensure a few protected sites in their lawn for bees. This article from the Great Pollinator Project goes into detail on how to help ground nesters and other wild bees.
Basically, some protected and sunny soil and leaving some dead branches on the ground or on shrubs such as sumac can help cavity nesters. You also can install artificial sites such as nesting blocks.
Plant Low-water Flowers
Plenty of favorite New Mexico flowers attract bees and other pollinators. Here’s a list of some of the popular choices of shrubs and flowers that grow in New Mexico gardens:
Agastache (also a big draw for hummingbirds)
Hollyhock (Alcea rosea)
Penstemon (with many native species for hummingbirds too)
The more months or seasons you have plants that attract bees in bloom, the better. We have some native, weed-like groundcovers that bloom in early spring, typically by April 1, that attract so many bees that we hear a low buzz sound all day when sunny. Leave flowers and seedheads on some annuals well into fall and frost danger to provide food for bees and birds. Even in higher mountain regions, native species of penstemon, beebalm and yarrow can bloom well into fall, as can hardy flowers such as gaillardia and cosmos.
Finally, a word about fear of bees. I get it – wasps and bees can be scary if they come after your dessert on the patio or buzz you when you get too close. But I have never had a sting while working in my garden, and the only time I recall ever being stung was when I was a child and running through the lawn barefoot. Even when I trim lavender stalks, the bees might buzz me, but don’t sting. And if you want to remove spent flowers from plants, choose low-light times of day, such as dusk, when bees are less active. Most of all, please don’t avoid plants that bees love just to keep them out of your yard. You’re not just helping bees or the environment at large, you’re supporting a mini ecosystem that makes sure tomatoes and other edible plants produce food for you and your family.
When approaching a new landscaping or planting project, it helps to gather ideas, whether you do so virtually or hopefully in person. A top benefit of being a member of the Association for Garden Communicators (GWA) is access to botanical, demonstration and private gardens.
If you travel, you can gather plenty of ideas from around the country. Even when I’ve visited the Northwest or Southeast, I’ve always found plant and design ideas or just enjoyed the gardens! If you want practical ideas you can apply in your own backyard, nothing beats a local botanical or extension demonstration garden.
Benefits of Demonstration and Botanical Gardens
Many botanical and demonstration gardens are designed primarily to educate. Extension master gardeners typically have demonstration gardens featuring native and zone-appropriate plants for their area. The city of Scottsdale, Arizona, has a xeriscape garden to demonstrate how local residents can save outdoor water use but have attractive lawns. The Albuquerque, New Mexico, Botanic Garden includes a demonstration farm that re-creates a 1930s farmstead to show how people can grow or raise their own food. And I love the Pollination Gardens at the Arizona-Sonora Desert Museum in Tucson.
The Tucson pollination garden teaches visitors about planting for pollinators, including Monarch butterflies. Most demonstration gardens help visitors learn about plants and especially how to grow them locally. But if you really pay attention, you also can learn a lot about design, containers and especially which plants or collections get you excited about gardening. Most gardens also offer classes or guided tours to add to the learning experience.
Finally, taking children to demonstration gardens can spark the gardening bug, especially for growing food. In fact, a study of demonstration gardens started by North Carolina county extension staff showed that between 2006 and 2010, the number of gardens made up of edible plants outpaced those with ornamental plants only or a mix of edible and ornamental plants to teach families about growing food.
Many demonstration gardens are run by extension offices of universities and the state extension’s master gardeners. Often, universities, cities and counties have gardens that serve dual purposes of beautifying office or park landscapes and teaching residents about gardening or local issues such as conserving water, saving pollinators, container gardening, producing food or gardening more sustainably. Hospitals can have meditation gardens on their grounds or demonstration kitchen gardens to help patients and families learn about growing healthy vegetables.
Others might be organized by private entities, and if touring an entire botanical garden seems overwhelming to the beginning gardener, or the gardener’s toddler, botanical gardens offer demonstration gardens within their exhibits. Visitors can make their way to the gardens on the map that interest them most. Remember, many demonstration and botanical gardens rely heavily on volunteers and fundraising to maintain their plantings.
Virtual Demonstration Gardens
Major botanical gardens might offer virtual tours, a nice tool if you can’t visit them in person and are researching local native or adapted plants for your own garden. If you’re on Twitter or Facebook, you also can follow favorite demonstration or botanical gardens and see photos or live videos. Or you can join an online community such as Plants Map to connect with other gardeners, organizations or resources that interest you. Organizations such as botanical gardens also set up collections on Plants Map.
Native plants should be the mantra of every xeric gardener. Let’s first review what makes a plant native and why native plants are so beneficial.
What is a Native Plant?
A native plant grows naturally in a particular region or location. To be termed “native,” a plant must have had no human intervention when it first set down roots. That doesn’t mean you can’t plant natives, just that the original plants were, well, original to a region and not introduced. The benefits of choosing native plants are many, including:
Water savings. Plants native to a region and climate should need less water from gardeners in prairies and mountains, relying mostly on Mother Nature alone. Even in areas where drought is less of a concern, native plants should get by on typical rainfall with little supplemental watering after the first year or so.
Convenience. Less watering means less time, in addition to the natural and financial resource savings! Native plants should be easier to maintain as well.
Helping pollinators. As natural areas such as forests and prairies disappear, usually because of development, bees and butterflies have fewer plants they can rely on for the energy they need. Planting natives helps them find nearby food sources. Attracting pollinators always is a good thing – they help tomatoes and other vegetable plants fruit, and your garden improves their habitat. Regardless of the many “right” reasons, you and your family can enjoy watching bees, butterflies and birds as the pollinators enjoy the buffet.
Better chance for success. Native plants are adaptable, so if you plant the right plant in the right location and follow care instructions, watering a little more than recommended in the first season or so, your job is easy after that.
Native Plant Resources
Now that I’ve convinced you to go native, where do you find native and pollinator plants for your region? Here are six resources:
Your local nursery, as in locally owned. You’ll find more knowledgeable staff on average here than at big box stores (such as Walmart or Home Depot). Local nurseries tend to grow and sell plants native to your area, and usually can answer your questions, even with some specifics on microclimates in your region. Catalogs that sell to your region or zone also can be helpful, especially in identifying pollinators (typically with an icon of a bee, butterfly or hummingbird).
Apps, especially from local sources. There are some great plant apps or mobile-friendly sites, including GrowIt! And Plants Map. For example, GrowIt! has a search feature for plants within a set radius of your location. As long as there are other members near you, it can be a big help. Plants Map includes communities, resources and individuals in its collections. A search could bring up your nearby botanical garden or private collections. Local apps from trusted sources such as extension offices are great for spotting natives. I use Southwest Plant Selector app, listed on my Resources page. In the future, watch for Leafsnap, a collective effort to offer visual recognition software to help you identify plants, much like a printed field guide.
USDA Plant Database. The Department of Agriculture has a database from which visitors can search plants by scientific or common name, and filter by state. It also has a state plants checklist (that looks like HTML code, unfortunately). This site is not sexy, but the best part about it is that once you find a plant you’re considering, a map comes up that indicates whether a plant is native to your state (green fill). It includes a lot of scientific information, but most plants have several photos to help verify identification and if you click on “legal status,” you can learn whether the plant is considered endangered or classified as a noxious weed in your state.
Native plant societies. The North American Native Plant Society has lots of information on natives, including a database searchable by type of habitat and this list of state plant societies. Those state groups with websites or newsletters can be excellent sources, and most offer inexpensive membership.
Friends, family and neighbors. If you see a plant you like, one full or butterflies, or remember a favorite from childhood, ask around. Even if a plant is not native, but seems to do well in your neighborhood, you can ask the homeowner or a local landscape designer about ease of care and hardiness.
Native Seed Resources
Growing natives and pollinator plants from seeds is less expensive, but can require a little more time and water initially. Here are a few sources for information on gathering or buying native seeds:
Xerces Society- In addition to pollinator plant lists for the United States (that unfortunately appear to exclude New Mexico, Arizona, Colorado and some other Western states), the society has a seed mix calculator to help with restoration efforts of prairies, etc., with native pollinator plants.
The North American Native Plant Society also has a seed exchange for members and information on collecting seeds from native plants.
Native Seeds/SEARCH is the top source for Southwestern native seeds. Their vault contains native crop seeds for low desert and high desert regions, along with wildflower seeds. It’s a wonderful combination of conservation and native seed resources.
Check out the Resources page for more information on buying seeds and plants native to your region.
New to gardening? Or just not a horticulturist, botanist or even a master gardener? Then you likely get confused by some of the terms you see on plant tags, in nursery catalogs and even in blogs like this one. You’ll enjoy gardening much more if you can weed through the jargon (and the puns). Here are 10 terms explained in plain language to get you started:
10. Xeriscaping. This one’s my favorite, of course. And as I’ve said before, it’s xeriscaping, from xeros, the Greek word for dry … not ZEROscaping. In other words, it’s planning a lawn and garden that uses the least possible water. In most cases, this means using drought-tolerant plants (see no. 1), but xeriscaping also involves using native plants adapted to your climate and conditions, along with lots of other strategies for landscape design and plant choice.
9. Perennial. The word means long lasting, and that’s pretty much true of perennial plants as well. A perennial grows in your yard for more than two years, often for much longer before it needs replacing. Remember that perennial varies based on where you live. For example, the well-known geranium can be a perennial in a warm climate, but I have to bring mine inside for winter. And don’t freak out if a perennial plant disappears or looks dead after frost. You’ll likely see new growth on it come spring. Planting mostly perennials in your garden usually leads to less work and less watering.
8. Biennial. A biennial plant lives for two years, or two growing seasons. Seeds start the plant’s root, stem and leaf growth in the first year, but the plant doesn’t produce flowers, fruit or seeds until the second year. After that, the plant typically dies, but can spread seeds before dying back. An example of a biennial is the foxglove (Digitalis). Another is one of my favorites, the columbine (Aquilegia), which might flower the first year, or might put all of its energy into leaf and stem growth, and then flower the following year. Some forms of poppy (Papaver) also are biennials. And unfortunately, some weeds also are biennials. They take on a tiny round leaf form, survive the winter that way and then flower and spread seeds, lots of seeds, the next year.
7. Annual. An annual lives only one year, or for one growing season. Still, some annuals re-seed, so if you’re willing to let Mother Nature design your garden layout, you can let annual flowers dry up and produce seeds. Annuals are great for small containers and adding color to a garden or patio each year. But they usually require more time, money and even water in the long run than perennial plants.
6. Native. A native plant was likely in your town before you moved in. These plants grow naturally in specific regions or conditions. They should not become invasive if they’re planted in their native region. The real benefit of native plants (aside from their beauty in the garden, forest or along roads) is that they’ve done most of the work already. They know how to survive weeks with no water or really high spring winds. Selecting native plants is one of the most effective xeriscaping strategies.
5. Specimen plant. Lots of catalogs refer to a bush or flower as a “specimen plant.” This has nothing to do with strange botany experiments. All it means is that the plant can stand on its own as a focal point in a garden or landscape design. For example, petunias or begonias look much better in mass plantings, which means groups of the same or similar flowers for a dramatic look. Mass plantings might become hedges or adorn the entry to your local mall. Landscapers might plant a row of 100 marigolds and a row of 200 petunias for striking color. On the other hand, a specimen plant shines all by itself.
4. Invasive. Typically, an invasive plant is a nuisance at the least. It can choke out other plants and grasses, climb around and choke bushes or simply compete for precious water. Invasive plants grow easily and rapidly, usually because they are not native to the area. Just remember that these terms are all relative. A plant native to a particular part of the country might be considered invasive after being introduced to a different region. When a plant becomes invasive, it probably crosses that very thin line between wildflower and weed. One of the most troubling weeds we encounter is field bindweed (Convulvulus arvensis), which is considered invasive in all of the lower 48 states, Hawaii and Canada. Maybe on the moon…
3. Deciduous. If a tree or shed is deciduous, that simply means it loses its leaves in fall and winter. The opposite would be evergreen, trees that keep their leaves all winter. Deciduous plants shed their leaves as a protection against upcoming cold. Many turn rich, deep shades of gold and bronze before falling, which gives the yard and garden color as summer flowers fade.
2. Pollinator. You might see list articles on blogs and social media mentioning “pollinator plants.” This means that the plant attracts bees and other insects that help promote flower and fruit production. The insects disturb and transfer tiny grains of pollen in flowers. Without bees, most fruit trees and many vegetables would produce little to no fruit. Many native plants, herbs and vegetables attract bees, butterflies, moths, hummingbirds and other pollinating insects to the garden. They’re essential plants to help maintain honey bee populations, which have been declining. Here’s a list of New Mexico pollinator plants. Many gardening books and catalogs place a tiny icon of a butterfly or bee in descriptions to let you know they attract pollinators.
And No. 1: Drought tolerant. Back to an important xeriscaping principle. Plants that are drought tolerant can go longer periods of time without water; it means basically the same as xeric, but is a little more direct. Plants with drought tolerance and resistance have characteristics that help them survive in these conditions. And all it usually takes is a little bit of rain to make them thrive, green and flower. Just remember – if you purchase drought tolerant plants, be sure to water them regularly for the first few weeks or months and up to the first year, depending on the plant and its size. The water keeps the plant alive through the shock of transplant and helps the roots get established.
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.
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.
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.
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.
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.
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.
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…
It smells fantastic, looks gorgeous, attracts bees and butterflies and needs little water or care. And on top of that, it’s a useful herb. Truly, I can find no drawback to growing lavender in the arid Southwest. Still, I’ve talked to several people while selling at farmers’ markets who say they had trouble establishing or maintaining lavender. So, here are a few tips, because I wouldn’t mind seeing lavender on every corner of every town.
Where to plant lavender
It’s tempting to plant lavender everywhere in the landscape! But the plant does best in full sun and with plenty of air circulation. So, if you plant lavender on the north side of your house, especially up against the house, it might not do well. You can also plant lavender in containers, but might have to amend soil around the plant after a year or two. Be sure to place the container in full sun and give the container plant a little more water than it would need in the ground — but not too much!
Lavender hedges are a summer stunner. But if you want to plant a row of lavender, be sure to leave plenty of spacing between the plants, and between the lavender and other plants or structures in your garden. It won’t look as full the first year. But by year two, you’ll love how the flower stems nearly touch but the plants have plenty of room. And foremost, plant lavender where you can enjoy the scent and pollinators the plant attracts. And check nurseries soon for a new variety from Sunset called “Meerlo,” which has variegated leaves!
When to plant lavender
Whatever date you think is right for lavender, push it back a week. Seriously, the only real problem we had with some lavender plants occurred when a group of new plants were shipped to us too far ahead of our last frost date. Fearing the plants were becoming rootbound in their small nursery pots, I planted as soon as the frost passed. But the ground and air were still a little too cool, plus the dirt did not drain as well as other spots in our garden. So that meant the new plants would stay wet after rain or watering. The only problem that really affects lavender is root rot. So be sure the ground and temperature have warmed up enough before planting.
How to plant lavender
First, make sure the variety of lavender you’re ordered or chosen at a nursery is a perennial in your area. Years ago, I assumed that French lavender (which really is from Spain) would do better in our climate than English lavender. It’s so cool and damp there! But French lavender is not as cold hardy. Most varieties of English lavender, however, can survive U.S. winters. Just check the zone when you buy.
Here’s the trick to success with lavender: Plant it on a small mound. This is a departure from typical attempts to save water by welling around plants. A well can hold water in longer, but lavender wants to take a drink and then dry out. Also, by gathering up a mound of dirt, you give the young roots some nice loose soil.
My second tip is to surround your lavender not with organic mulches, but with tiny white pebbles or decomposed granite. Doing so still allows water to penetrate, but gives the plants reflected sun and passive solar heat gain. If you use rocks and have as many weeds as we have, you’ll need to try and get the mulch layer at least three inches high. But leave a border several inches around the new plant on every side so the rocks don’t crowd the lavender base and constrict growth. Water more often than the plant tag says for a few weeks or more, until the plants look settled in their new home. But let new lavender plants dry out a little between watering or rain.
How to care for lavender
So, you have your lavender established. The hard part’s done! All you have to do how is harvest the gorgeous flower stems as the flowers begin to open in summer. In warmer climates, you often get a second bloom. We’ve found that our second bloom in zone 6B is pretty sporadic, even lousy. So it’s really a matter of choice – you can harvest early and enjoy the scent inside your home, or leave the stems on the plant to enjoy its color and share its fragrance with pollinators.
Just be sure to trim the stems off – right at the top of the leaves – at the end of summer or in early fall. Don’t worry if your plant turns a little gray in winter; it should begin to green up along with other perennial plants in spring. As new leaves begin to emerge in spring, trim your plant for shape and health. That means avoiding cutting down into the woody stems. I give mine a nice round shape. So simple.
That second year, your plant should need little to no watering. I typically give lavender plants some water right after trimming in spring and then only water if we have severe drought.
The stems are easy to dry and place in a vase or use harvested buds to make sachets or potpourri. Lavender is great in homemade gifts and even as an edible.
Our low-water garden has lots of yellow. Maybe that’s true everywhere. And it’s a bright, happy color. But we like a little more variety, and it’s easy to add pops of color a little at a time, or with annual plants. Here are a few tips for finding plants of many colors.
Find flowers by color
Although you’re used to a favorite flower blooming in a particular color, there likely are hybrids with colors you hadn’t considered. For example, we think of sunflowers as bright yellow, but I love the cinnamon varieties. I’ve got some seeds in again, in the hopes that bugs and deer leave them alone.
One way to find flowers in complementary colors is by using apps and online databases. For example, the LadyBird Johnson Wildflowercenter’s database includes bloom color, along with native states and sun and moisture requirements in its combination search. For a simpler search, try a list like the one maintained by ProFlowers, which lists flowers by color next to illustrations and a brief description. Just beware that national lists of flowers often include varieties that do poorly in some zones or soils or need more water than those in a xeric garden. Be sure to read the descriptions or do a little research before making your final decision. You can also try apps that either have pictures shared by posters or plant identification. If you can find a local or regional app, even better.
Wander around a nursery
If you feel a national list might isn’t giving you enough choices for your area, visit a locally owned nursery. Although they’ll carry some annual varieties that aren’t perfect for the community’s climate, they also carry plenty of knowledge and tend to feature plants that are native or adapted to local growing. If you do find a few annuals either at a local or chain nursery, limiting the number to a few pots or a corner of a bed uses less water, time and money than basing your garden color plan on annuals. Most nurseries separate perennials and annuals to help shoppers.
Make notes as you pass homes and businesses
If you’re walking to a restaurant in town one night and spot a flower with a color you love or know would add variety to your garden, take a photo of the plant and a close-up of the flower. This will help you compare what you saw (and photos work much better than memory) with identification apps, databases and local gardening books. Including the entire plant in the photo helps you remember the type of foliage, height and spread of the flowering ornamental.
Color really is a matter of personal choice, and with the recent National Pollinator Week in mind, I try to choose a few new plants for their ability to attract bees, butterflies or birds. For example, studies have shown that bees gather more nectar from purple or violet flowers than from any other color.
Keep it simple and choose what you like, but remember not all plants bloom at the same time, so your color variety might be seasonal or in stages. That’s great too though, so you and the pollinators can enjoy some new blooms every few weeks.
