Plant and Repeat

One of the best features of many xeric gardens is the natural look of the landscapes. We often use rocks and boulders and tuck native plants among them. This design most closely mimics the look of the landscape around us.

rock-garden-plants-southwest
Here’s a perfect example of a Southwestern xeric design that’s natural, too. This bed at the entrance to Plants of the Southwest nursery in Albuquerque repeats some plants, but otherwise mimics nature.

If you’ve moved to New Mexico and other Southwestern states from areas of the East and Southeast, you might be more used to a cottage garden look, where shrubs like boxwoods form hedges and foundation plantings repeat the same flower.

grasses-rows-garden
This Austin garden early on our tour inspired the idea to look for repetition. Rows of grasses have order, but look natural and likely help with erosion control.

On a recent trip to Austin, I noticed a perfect blend of both features. Many of the gardens I toured with fellow garden bloggers struck me with how well they used repetition in their designs. But these Texas gardens also had a natural look. Here’s a photo essay from Austin, along with a few New Mexico shots.

So, Why Repeat Plants or Containers?

I realized we tend to favor single plantings in our gardens, typically choosing a plant based on how it will look in a location or complement a nearby plant. And when you love plants, it’s tough to resist adding any you like to any garden you own. But after seeing the use of repetition, I decided we need to add more repetitive elements. Here are a few reasons why:

lavender-plants-row
One area of repetition in our rock garden is the lavender. This is the top row.

Continuity. A garden is a sort of composition, and repeating an element gives it a sense of balance without making it look too symmetrical or monotonous.

repeated-potted-plants-patio-table
This patio table at Tanglewild Gardens uses repetition in its centerpieces, but repeats natural elements.

Easier maintenance. We all have a plant we’ve tried that survived despite strange weather or a little neglect. Others require little to no pruning or deadheading. Why not scatter a few more of these easy-care plants around your home?

container-plants-three-iron-heart
Pam Penick’s awesome front garden included this container with three of the same plants and a beautiful piece of garden art. The plants have the same watering and exposure requirements.

Color. Although many xeric plants are colorful, some really stand out in the garden. Using the same purple in a row of plants or throughout a garden gives a color focal point.

succulents-containers-color
Lucinda Hutson’s garden was packed with color. Here, she used the same three succulents in colorful matching containers.

Saving money. Sure, you still have to buy the plants, but it is less expensive to buy four of the same perennial once than to fill in an empty space in the garden each year.

b-jane-gardens-repeated-plants
This garden, built and designed by B. Jane Gardens, repeats these plants in a shady raised bed, but the effect is visually appealing and far from formal.

Finally, I would say that repeating plants is a fine example of xeriscaping principles. When you plant 5 native grasses in a grouping, they all have the same water and sun exposure needs. You don’t have to come in and add water for a plant that needs more than the grasses or take the chance of overwatering and killing a nearby plant. And when you use repetitious art or hardscape elements, you add to the design without adding plants — and that requires no water at all!

Santolina: You Can Grow That!

gray-santolina-yellow-blooms
The bright yellow blooms and silvery foliage of gray santollina.

Santolina is an herb said to be used in folk medicine to make a tea that expelled intestinal worms or was used as an eye wash. The plant repels insects, and placing leaves in sachets is said to repel moths.

We grow santolina (also known as lavender cotton) in our rock garden for its evergreen appearance, yellow button-like flowers and drought tolerance. It’s not native to North America, but does very well in our dry Southwest soil.

gray-santolina-foliage
The silvery-green, almost lacy foliage of gray santolina up close.

Gray santolina (Santolina chamaecyparissus) produces bright yellow flowers in summer. The plant has few matches for attractive gray-green foliage and its ability to spread as a groundcover. Our large one has been a cover for a litter of cottontails and is now spreading slowly over a rock wall.

gray-santolina-pruned-rock-garden
New growth on a gray santolina (right after spring pruning) cascading down a rock wall.

Another variety, green santolina (S. virens or S. rosmarinifolia) has lemon-colored button flowers that contrast with its deeper green foliage. Both types of santolina have an aroma, and some people find the bloom aroma offensive. Most varieties of the shrubby groundcover grow in zones 5 through 9 and need only moderate water. Learn more about santolina varieties from Cornell University.

lemon-colored-blooms-green-santolina
I love the lemondrop look of the green santolina flowers.

Caring for Santolina Plants

The plants prefer full sun, but our largest santolina blooms each summer even though it now gets lots of afternoon shade from a nearby tree. Place the plant in well-draining soil. When temperatures reach 90 degrees, water your santolina every few weeks if you get no rain. Otherwise, it needs water only monthly or less.

green-santolina-before-gopher-spurge
Even before blooming, green santolina is a nice companion for the light green foliage of gopher spurge.

Prune (really, shear) santolina shrubs in early spring to shape and remove dead flower stems. Every two to three years, give the plant a harder prune down to about 6 inches above the ground to keep the plant from getting leggy. You also can sheer dying flower stalks after the first bloom for the chance of a second summer flowering.

green-santolina-not-pruned-enough
I did not prune this plant low enough a few years ago, and it is a little leggy and less rounded. Still, it has an attractive, natural shape.

The plant is evergreen or semi-evergreen in some climates. Santolina does best with no fertilizing. How easy is that? And you can take cuttings or divide larger portions of the plant in fall, although the transplants might succumb to cold, so if you can warm them the first winter, even better.

Whether you grow santolina for its herbal properties or appearance, you can grow that!

 

5 Easy Plants for Xeric Gardens

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.

desert-zinnia-chimenea-pot-with-lobelia
Desert zinnia adorns this low-water rock garden.

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

moonshine-yarrow-blooms-leaves
Moonshine yarrow is easy to care for, transplant and grow in low-water gardens.

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.

moonshine-yarrow-blooms-closeup
Here’s a closer look at yarrow blooms. Pollinators love them as landing pads.

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.

Ornamental Grasses

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!

karl-forester-feather-reed-grass
Karl Foerster Feather Reed Grass (Calamagrostis acutiflora Karl Foerster) in our dry river bed in midsummer.

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.

purple-fountain-grass-seeds
The flower stalks of Purple Fountain Grass.

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 Zinnia

desert-zinnia-blooms-foliage
Prairie or desert zinnia spreads easily in sunny, dry locations.

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 Spurge

closeup-gopher-spurge-stalk
The foliage stalks of gopher spurge are attractive all year long.

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.

euphorbia-blooms-yellow-red
Gopher spurge blooms early in our zone 6B xeric garden. This is in March.

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.

Coreopsis

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.

lanceleaf-coreopsis-sterntaler-blooms
Tickseed (Coreopsis lanceolata Sterntaler) blooms all summer with a little deadheading or shearing.

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.

Favorite Flower: Nigella

I just discovered this delicate, early bloomer in the past few years when friends suggested Love-in-a-Mist (Nigella damascene) seeds from our local iris farm. The foliage looks much like fennel or dill as seedlings sprout, and nigella also is called fennel flower.

pink, purple and white love in a mist flowers
Love in a mist grows from between rocks bordering our xeric garden.

Nigella Is Versatile

We grew multicolored love in a mist in our rock garden. Tim threw the seeds out in fall and by mid-spring, we had fine fern-like leaves popping up from between the rocks. Although Nigella does best in damp sandy soil, ours grew out from under rocks that make up the walls of our xeric garden. The rocks likely held moisture longer than a spot in the open might have. The rocks also trapped the tiny seeds so fewer blew away. Plus, nigella can tolerate dry conditions.

Here are the same flowers from a wider angle — in the corner to the right of the potted geranium.

But then we tried another approach – we bought a packet of Bridal Veil (Heirloom White Nigella) seeds from Renee’s Garden and sowed them in early summer in a blank spot of our vegetable garden. This soil is far better in quality, and the seeds received consistent drip watering. The flowers were taller and stunningly white, with maroon to black centers. The plants reproduce from seeds, assuming some seedheads are left on plants at the end of the season.

These heirloom bridal veil flowers thrived in our vegetable garden and the contrast of colors is gorgeous and fun.

Sow in Fall or Spring

Although most instructions for growing nigella say to sow in spring, you can sow them in fall in areas with mild winters. They need full sun and grow in zones 2 through 10. That worked well for us last year, but this winter has been dry and consistently colder, so I’m anxious to see how many reseeded in our gardens. The bridal veil flowers in our vegetable garden bloomed later in the year, but were planted later. Sowing the seeds a few weeks apart in spring and fall can help ensure constant blooming of nigella in summer.

overhead view of love in a mist
The many colors of love in a mist add interest to the garden or flower arrangements.

Use as a Cut Flower

You can cut nigella blooms for flower arrangements, and even better, cut some of the seedheads. If you cut the flowers to enjoy indoors, leave a few blossoms on the plant so they can dry and drop seeds for the next year. If you get too many, thin them out while small. Enjoy the seedheads after flowering by cutting their stems just after flowers fade, and hang them upside down away from direct sun.

Nigella is easy to grow and a great addition to any xeric garden!

Five Low-water Plants for Winter Birds

stellar jay in garden
Stellar jay in line for raw peanuts in late fall.

As winter drags on, birds need lots of energy and shelter from the elements and predators. The best bird habitats mix shelter, water, natural seeds and nest-building material as spring approaches. Native plants offer many of these benefits, and the more varied a landscape, the more bird-friendly it is. For example, birds in our garden “stage” their visits to feeders or the ground by moving between the thorniest rose bushes and higher trees.

woodpecker and sparrow on bird feeder
Birds use low bushes as staging spots before visiting the feeder in our redbud.

Here are five plants or plant types that make birds safer and happier when temperatures drop without adding a lot to your work, or to summer watering requirements.

stellar jay on ground in rock garden
We have lots of spots in our garden where jays hide peanuts.

Native grasses

blue grama grass meadow
Blue grama and wildflower meadow. The grama seed spreads and feeds birds, who also help disperse the seed further for us.

Replacing at least some of your turf with native grasses and other native plants helps birds and uses less water. We purposefully leave our native grasses (mostly buffalo and blue grama) long as it dies back in fall to increase  shots at reseeding and filling in bare spots. The seeds also provide food for ground-hopping birds, additional food caches for jays to hide the raw peanuts we put out, and dried grass stalks for nests before the grass greens in summer.

Ornamental grasses

Karl Foerster grass

Switchgrass, big bluestem and muhly grasses all provide seeds and nesting materials for birds. Karl Foerster feather reed grass (Calamagrostis acutiflora “Karl Foerster”) attracts birds and is a beautiful winter plant, with tall seed stalks that blow in the breeze. There are hundreds of species of the grass, and it grows in zones 5 through 9. Its water requirements are a little higher than some native grasses, but if you plant Karl Foerster grass in a rain garden or low spot, it will get more water naturally and won’t be hurt by the damp soil.

Barberry

Barberry (Berberus) is a hardy shrub with small thorns along its branches. Depending on the variety you choose, you’ll enjoy deep red or pinkish foliage. The shrubs grow in zones 3 through 8 and retain their leaves in winter in most conditions. Fragrant yellow flowers emerge in spring, and the prickly branches provide good cover for small birds. You can plant several barberries a few feet closer together than recommended to create an attractive, bird-friendly hedge.

Boxwood

Boxwood (Buxus) normally isn’t considered a low-water plant, and I’ve seen countless examples of boxwood to form formal hedges and designs in other areas of the country. It is an easy plant to shape, and makes such a good hedge because its evergreen foliage is so dense.  That’s also why birds love boxwood. Although boxwood might look a little formal for a native rock garden, we use ours as a foundation plant near our front door, where we want a more landscaped effect. Since it’s also on the north side of the house, I’m sure birds hide under the bush for cover. The boxwood’s protected, mostly shady location and slow growth habit help the shrub stay healthy with less water than it might need in a sunny spot.

Pyracantha

pyracantha berries

Pyracantha shrubs produce berries in late fall to feed birds as temperatures drop. Also a thorny bush (sometimes called Firethorn), pyracanthas provide safe shelter for birds. What I love about the shrub is the diverse ways you can use it in a Southwest landscape. Leave it to grow naturally (maybe with some shoot trimming after rainy summers) or shape it like a hedge. We had several growing along a distant fence and Tim moved one to the front of the house. The pyracantha transplanted without a blink and just a few scratches. We leave the remaining two out in the yard in their natural state and shape the one in front of the house. I get to see the berries from my kitchen window and saw a Stellar jay eating them this past fall.

Many native shrubs  attract birds in winter. Berries, seeds and bushy cover all support wildlife. Ask your local nursery or master gardeners for the best low-water plants in your Southwest zone.

5 Drought-resistant Groundcovers

Groundcovers might not be as sexy or exciting to plant as some ornamentals, but the low-growing plants are useful and can really add to a xeric garden’s look and function.

Prairie zinnia
Prairie zinnia covers ground and rocks. Anything that grows in rocks gets by with little water!

Here are a few reasons and ways to use groundcovers:

Water savings: erosion control. On garden slopes, a low-growing groundcover slows the flow of water. Use one that’s relatively drought tolerant and the plant absorbs enough water from the flow to get by. An added bonus – slopes can be difficult to mow, and a low-growing groundcover needs less maintenance.

Water savings: mulch effect. Groundcovers cool the soil below and retain some moisture, which can work as a sort of living mulch under a tree or other plant that needs cooler roots.

Turf alternative: Groundcovers typically are less invasive and easier to control than grass, especially between flagstone or other steps.

groundcover between stones
I believe this is ajuga between flagstones in a private Atlanta garden. It creates a sort of woodland look.

Weed control. Once a groundcover blankets an area, weeds have a harder time growing in the same spot. It might not entirely eliminate them, but eventually weed seeds have a harder time getting into covered soil and receive less light.

Design element. Groundcovers can add color, year-round interest and an area of low growth in the foreground of a design or near paths. Check out this gorgeous example of creeping thyme as an alternative lawn in a xeric design.

  1. Creeping thyme (Thymus ‘Pink Chintz’). This is an excellent choice for filling in around flagstone steps or any area that takes foot traffic (see link above). In fact, several thyme varieties are considered steppable. Creeping thyme does fine with low water once it’s established, but if it receives more water, it grows more rapidly, which might help to fill in an area.

  2. Ice plant (Delosperma). The flowers of ice plants are delicate and bright, coming in yellow, bright pink or salmon and rust colors. Although some varieties of ice plant need a little more water than others, most can get by in xeric rock gardens. Ice plant is a rapid spreader and easy to maintain. If it grows outside the area you intend, just clip it off. Or pull up a stalk and its roots and move it to another spot in your garden.

    purple ice plant

  3. Perky Sue (Tetraneuris scaposa). Although Perky Sue might not technically be a groundcover, it can spread enough to add floral color and evergreen foliage. I’ve seen this or a nearly identical plant called plenty of other names, including Hymenoxys scaposa, bitterweed, and narrow four-leaf nerve daisy. It’s also similar to the Angelita daisy (T. acaulis).

    Perky Sue
    Perky sue has silver-like foliage and yellow daisy flowers.
  4. Prairie zinnia (Zinnia grandiflora). Also called desert zinnia, this is a favorite rock garden groundcover of mine. It has tiny, thread-like leaves and bright yellow flowers. Most of all, it spreads from the previous year’s plant; you simply remove the spent foliage as the weather warms and you see new green beneath the old. It can spread up to 6 or 10 feet.

    zinnia grandiflora shadow
    Delicate, spreading and xeric. The prairie or desert zinnia.
  5. Plumbago (Ceratostigma plumbaginoides). The best part of plumbago is its fall color. The purple flowers typically bloom in early fall and then the leaves redden. Plumbago also does best in shade or part (afternoon) shade in warmer areas.
groundcovers rock gardens
Veronica is another low-spreading groundcover for rock gardens. A Perky Sue bloom is peeking out on the left — in March!

All of these groundcovers are perennial and hardy to zone 6 or cooler. Groundcovers can require some patience or money. For carpet-like coverage, you either have to plant many of them fairly close together, or ideally space new plants according to planting instructions and wait for them to fill in. Some also have minds of their own. To me, the haphazard growth is more natural looking in a rock or xeric garden. But if you’re going for a formal look, choose one that’s easier to control, such as thyme.

Plant Select’s Top High Plains and Intermountain Plants

Each year various societies present plant awards, but those of us who garden in the West and Southwest await the group of Plant Select top performers. Plant Select, which is a nonprofit joint effort of Colorado State University in Ft. Collins, the Denver Botanic Gardens and professional horticulturalists, lists five top performers at various elevations.

First, a word about why the work of Plant Select and other regional groups is so important. As I said, there are plenty of awards and lots of information in the gardening world. But, for the most part, plants emphasized by magazines and bloggers are great for East Coast and Southeastern region gardeners. It’s different in the high plains and intermountain areas of the country, where altitude, wind, and heat and cold extremes (in a single day and by season) affect plant health. And let’s not forget the water issue.

Plant Select evaluates plant performance in 53 locations throughout five Western states. Here are some of the 2016 Top Performers. See the entire list at Plant Select.

Grand Winner: Blonde Ambition Grama Grass

Blonde Ambition grama (Bouteloua gracilis ‘Blonde Ambition’ PP22,048) was introduced by New Mexico’s David Salman of High Country Gardens (American Meadows). Blue grama is a perfect low-water native grass grazed on by cattle on our Southwest ranches. Salman introduced the blonde ornamental variety in 2011, and this is the second year it has been Plant Select’s grand winner. Beginning in July, chartreuse blooms (seedheads) appear on upright stems, turning to the blonde color as they age. Watching those seedheads wave in winter winds provides xeric gardeners some year-round interest in their landscapes. Although Blonde Ambition can spread by seed, the seedlings are easily pulled up. The grass is hardy in zones 4 through 9 and deer resistant.

Top Performer at 3,000 to 5,500 Feet Elevation

Blonde Ambition also tops the list of lower elevation garden performers in the region. Number 2 on the list is a tree I’ve never grown, but want to learn more about since it also topped the list for gardens at my altitude (6,300 feet). The Hot Wings Tatarian maple (Acer tataricum ‘Gar ann’PP15,023) has bright red samaras, or fruit made of paper tissue, that bloom all summer. It’s also known for its reddish-purple fall color. The Tartarian maple is a relatively small tree, maturing to nearly 18 feet high and wide, and gets by with full sun and moderate to dry water needs. The only drawback for me is that it is not deer resistant, but I could see this gorgeous tree in any suburban garden from 3,000 to 7,000 feet in elevation and in zones 4 through 10. We still might try it, but we’ll have to fence the tree until it reaches a mature height and keep lower limbs pruned.

Top Performer at 5,501 to 7,000 Feet elevation

Although the Hot Wings maple topped the list of performers at this elevation, I would like to give a nod to No. 2 on the list – Turkish veronica (Veronica liwanensis). Veronica is an excellent low-water groundcover. Veronica is evergreen, so it covers portions of our rock garden all year long. In summer, the groundcover blooms. Turkish veronica has cobalt blue flowers above waxy leaves. It only reaches about 2 inches in height, but can spread to 18 inches wide. Although veronica is a xeric plant, its leaves look better with a little extra water in the heat of summer. Turkish veronica is hardy in zones 3 through 10 and deer resistant. The top 5 Plant Select performers at this elevation also include Blonde Ambition, Apache plume and a catmint called Little Trudy (Nepeta ‘Psfike’ PP18,904).

Top Performer in Gardens Higher than 7,000 Feet

Fernbush (Chamaebatiaria millefolium) topped the list for higher elevations. The Western native shrub is xeric once established and grows more upright with less water. It can look more formal with rounded pruning in early winter. Deadheading spent flowers also makes the plant look neater, and should be pleasant considering that the foliage has a honey-like scent. The sweet scent also deters deer. Fernbush can grow to nearly 5 feet high and wide; less water keeps it more compact. The plant thrives in full or partial sun in zones 4B through 8.

Watering Cacti and Succulents

Succulents are low-care starter plants for anyone easing into gardening or short on space. Best of all, they’re typically the lowest water users of the plant world. It’s often said that cacti and succulents thrive on neglect. Although that might be true when it comes to maintenance such as trimming or fertilizing, cacti and succulents do need a little attention and consistent, light watering.

barrel cacti
Rocks, heat, hills that drain water. These conditions make cacti happy. This image was taken at the Huntington Library and Botanical Gardens in San Marino, Calif.

Water Sparingly

The common characteristic of succulents is that they have adapted to surviving with little water. Cacti are tough, and about the only thing that will kill them (other than being munched or trampled  by wildlife) is overwatering. In general, about once a week is perfect. Set a date every Saturday morning, for instance, to water and check on indoor succulents. The best way to water container succulents is by making two trips – water your succulents once with a slow, steady stream. Don’t give them so much water that it runs out the bottom of the container, but give them enough to soak in past the surface. Then come back and give them a second drink, which makes for a deeper and more even watering.

agave parryi in snow
These agave survive outdoors here in zone 6B. We don’t water them, but from time to time, nature does the job.

The best watering for outdoor succulents is through a steady drip. How much depends on conditions, just like with other plants. When heat is extreme, cacti and succulents need a little more water. When it rains, you can skip watering altogether. If you bring cacti indoors for winter, they need a little more water in a hot, dry and sunny room.

Transplanting and Repotting

Have you ever seen a photo of an avocado pit in a glass with roots sprouting from the pit? Like most plants, lots of water encourages roots to grow. The same goes when placing most new plants in the ground or a new container—extra, deep watering helps roots establish. But that’s not true of succulents. They need time to heal before you water. In fact, taking a cutting from a cactus to grow a new plant (propagating) means letting the cutting rest and dry before putting in soil!

cacti in sunny window
Tim propagated many of these succulents from cuttings.

If you want a mixed arrangement indoors or out, try to make sure your cactus or succulent receives only the water it needs. In the landscape, you can mound the dirt under the plant slightly so that water drains to nearby plants with higher water needs or have a dedicated drip for the succulent that emits less water. Avoid spray irrigation, especially on succulents. In container arrangements, keep your cactus in a small plastic container half-buried in the container’s soil. This helps the gardener pour more water to flowers around the cactus than directly on it, which helps keep the cactus soil from getting soggy.

Do a Little Research

All cacti are succulents, but not all succulents are in the cactus (Cactaceae) family. In general, succulents are known for their fleshy leaves that hold water. Their leaves usually are small as well – leaving less surface for transpiration, which is the plant equivalent of evaporation.

Baby toes (Fenestraria) are so-named for their swollen ends, a classic succulent survival feature. The flowers are pretty awesome too.

Just like with trees or flowers, every type of cactus and succulent is a little different. For example, Adenium, commonly called desert rose, is a gorgeous succulent member of the Apocyanaceae family, the same one that includes oleanders. Knowing that helps: First, the only true pest of adenium is an oleander caterpillar. Second, although technically a succulent, when the plant is in full leaf and flower season, it needs a lot of energy (sun and water) and can be treated more like a tropical plant. But adeniums drop their leaves in winter, even in indoor containers. When they go dormant, they need little to no water.

The Desert Rose (Adenium) drops its leaves in winter and needs little water while dormant (resting). When it starts getting flower buds, it needs a little more.

In fact, that’s true of nearly all cacti and succulents – they need more water (and some fertilizer) during their growing/flowering periods and just enough to get by when dormant. Most will flower and grow in spring, fall and cooler parts of summer. High summer heat can make them dormant as a survival tactic.

It’s easy to research cacti and succulents in regional garden books and online, using reputable and regional sources when possible.

Repotting

Although most cacti and succulents grow more slowly than typical garden or house plants, they can outgrow their pots. In addition, succulents grown in pots and watered from a tap can have problems when minerals from the water build up in the soil. That’s a second reason to repot. You can avoid the mineral build-up by using rainwater for cacti and succulents instead of tap. Be sure your plant is in a container that drains well. That means drilling holes in the bottom of any containers that lack them and filling them with planting medium only (no rock or other filtering materials at the bottom).

The split rock cactus (Pleiospilos nelii) is native to South Africa and does well in a container, as long a you cut back on water in the heat of summer and cold of winter.

Of course, soil, location or zone and other factors affect the health and water needs of cacti and succulent. But most adapt to soil and environmental conditions.

Five Starter Waterwise Plants

Need to ease into saving water in the lawn? Or just ease into gardening? As you think about next spring and ideas for improving both the look and sustainability of your lawn or garden, consider adding easy-care plants that need little to no watering. Here are five ideas:

Yarrow is an easy xeric plant

Rosemary (Rosmarinus officinalis). The woody, herbal rosemary is near the top of my list of favorite xeric plants. The only problem you can have with rosemary is if it receives too much water (or snowpack in winter). Otherwise, try a creeping rosemary near a rock or low garden wall. The stems will grow over the surface and you can trim it in spring just to keep it clean and healthy. I’ve seen bushier varieties shaped into small hedges. And man, what a great-smelling hedge! Finally, be sure to plant a rosemary near your kitchen so you can head out and clip cuttings for cooking use anytime of year (at least in zones 8 through 10). We have rosemary plants that come back each year here in zone 6B. They’re near the house in a rock garden, which helps warm them up. Plant rosemary in full sun and only water occasionally after its first season in the garden. Rosemary plants also reward you with tiny lavender-colored flowers in summer. And although I love the taste of rosemary, deer leave them alone. Bonus!

Barberry (Berberis). Barberry comes in several varieties that do well in plenty of sun (or partial shade) and low water. Berberis x ‘Tara’ Emerald Carousel is a type that grows well in alkaline soils, the kind we have here in New Mexico. Depending on the variety, barberry grows a little wider than high. Some Japanese barberries can grow tall – up to 10 feet – so consider that when selecting a plant. Barberry leaves change color with the season, and I’ve seen lime, orange and deep red varieties; they’re all stunning. Several plants along a wall can form a hedge in front of a house or fence. We like the spiky red foliage for its color and texture in our garden and deer usually avoid the plants. Barberries might need a little more water in the first year or so than some plants listed here. After that, they can handle periods of near drought or drought. All you have to do is prune them once or twice a year to keep the shape or size you like. Be sure to wear gloves!

Yarrow (Achillea). Yarrow is considered an herb, but I grow it for its easy care and stunning colors, which include white, yellow and red varieties. Moonshine yarrow has bright yellow flower clusters that you can cut for arrangements. I also pressed a few this year. This truly is one of the easiest plants to grow. Each spring, you simply cut off the dead flower stalks and clean up the plant. By mid-summer, you’ll have color. I even tried trimming spent flowers off one of our yarrow plants this year to see if that would force a second bloom sooner. But the ones I didn’t trim had more blooms in the second wave of flowers than the one I trimmed. Lesson learned. After the initial spring trimming, just leave yarrow alone. The plant also spreads but not invasively, so consider that when placing it in a design. We dug up one that was too close to another plant and transplanted it near our farm to attract butterflies and bees. It needs a little more water when first planted or transplanted. After that, it can get by with no water in all but the most severe droughts and survives winters down to zone 3.

Four-wing saltbush (Atriplex canescens). Native Americans used many parts of the native four-wing saltbush, including leaves and boiled roots, for food or medicine. It’s also useful to wildlife, grazed by deer and antelope. The name for the bush comes from the four paper-like wings that surround its seeds. There’s no real care needed for saltbush, especially in a natural garden, but you can trim it as desired. When saltbush flowers, it takes on an attractive two-tone effect. The native plant is easy to grow in any soil, and can pop up around roadways in New Mexico. Ours grows far from the garden along a fence. We don’t know if the former owners planted it or if it came up from seed. If you’re worried about it spreading, just learn to recognize the plant’s needle-like leaves and pull up any small plants in your garden or yard.

Jupiter’s beard (Centrathus ruber ‘Coccineus’). At first glance, Jupiter’s beard (also called red valerian) doesn’t look like much. The flowers rise above thin, pointed, pale-green leaves. So it’s a lot of foliage mixed in with small, coral-pink flowers. But these flowers pack a punch! They’ll bring bees and hummingbirds to your garden all summer. And they grow best in dry, hot conditions. Still, red valerian can survive frost down to zone 3, or about -30 degrees F. All you have to do is give Jupiter’s beard a sunny spot and water regularly the first spring and summer. Then you can pretty much leave it alone. We water once in spring, depending on rain. You can cut back old leaves and stalks in spring to give energy to new growth. The plant reaches about 2 feet high and wide.

Wildflowers and Deer

We’re trying to add more wildflowers to our garden and create small meadows around some areas of the property. One of the challenges in choosing locations and flowers is munching deer.

Deer grazing in winter just a few feet from the house. The stucco buckets cover some succulents that need extra heat and deer deterrent.

Our deer population is not huge, mostly because of a previous wildfire in the forest north of us. I don’t want to exclude deer from the property and am happy to let them graze our grama and other grasses all year long. Although we seldom see the deer once summer days heat up, we see evidence of their munching from time to time.

Blocking deer is the best way to keep plants safe. But it’s much easier to fence around a tree, bush or vegetable garden than it is around a wildflower meadow. Fencing kind of ruins the effect. So, the best way to keep deer from eating the flowers is to plant “deer resistant” varieties. The quotation marks refer to the fact that our deer have not read the plant descriptions. They avoid several plants completely, but every so often, we find surprising telltale signs of deer damage. I think it’s difficult to guarantee deer resistance for most plants.

Deer-resistant wildflowers

We recently ordered a deer-resistant wildflower seed mix from High Country Gardens that we’ll plant after the first hard frost. Not all of the plants bloom the first year, which is disappointing, but we’ll plant a few deer-resistant annual plants to fill in so the meadow looks colorful for a special event we’re hosting next summer. Here are some of the flowers included in the deer-resistant wildflower mix:

Yarrow (Achillea millefolium); Lanceleaf and plains coreopsis (Coreopsis lanceolate and C. tinctoria); Foxglove (Digitalis purpurea); California poppy (Eschscholzia californica); red poppy (Papaver rhoeas); and the trusted blanketflower (Gaillardia), along with several types of lupines (Lupinus) and sages (Salvia).

california poppies
California (Mexican) poppies from seed. The young plants had a little deer damage, but recovered. We’ve left late seedheads on the plants hoping they’ll spread.

This wildflower mix needs full to partial sun – at least six hours of sun a day. We have a few areas that are shadier, so we’re still looking for an easy solution there. In April, I wrote about five drought-tolerant plants that love shade. Columbines come to mind, of course, but some salvias take at least partial shade and are deer resistant. Then again, some shade lovers, like hostas, attract deer. We’ve also got some rocky areas, and plan to sprinkle white love-in-a-mist (Nigella) seeds and gathered larkspur (Delphinium consolida) seeds this fall as well.

salvia and paper flower
Most wildflowers and low-water perennials need some sun. Some types of salvia can tolerate partial shade.

Keeping deer out of meadows

One strategy for keeping deer out of wildflower patches is to surround the area with aromatic plants that deer avoid, such as lavender or rue. There are lots of deer deterrent products; I’ve had success with Messina’s Deer Stopper spray on plants in our xeric garden that deer had previously disturbed. The product remains effective for about 30 days, but I have to remember to spray regularly for continued protection. Spraying an entire meadow would take way too long, but I think the spray could be really effective on those flowers we’re most concerned about or know deer have eaten in the past.

Finally, if uncertain about the best wildflower choices for a meadow, work with what you have. You can try gathering seeds from native plants or leave the area unmowed at the end of the season and let nature spread the seeds for you. I’ve done that in an area with a higher grama-to-weed ratio, and hope that each time I walk through it, I spread grama and flower seeds. We pulled as many weeds from it as we could to give the native plants like grama, wild blanketflowers, verbena and daisies a better chance of reseeding.

Note: Messina’s sent me a free sample of Deer Stopper spray, but did not influence my use or review of the product.
