What is Xeriscaping?
Xeriscaping is a term based on the Greek word xeros, meaning “dry.” It is a garden designing technique in which any plants rely largely on natural rainfall rather than heavy irrigation. It’s especially popular in the Southwestern US which experiences severe drought and desert conditions. Not only is xeriscaping design an ecologically responsible choice, it also frees up a gardener to travel or enjoy other activities.
7 Principles of Xeriscaping
There are seven principles of low-water garden design you should be aware of:
- Planning and Design
- Soil Improvement
- Limited Turf Area
- Efficient Irrigation
- Low Water-Use Plants
- Low Maintenance
It may sound complicated, but incorporating drought tolerant plants will actually save you time, money, and of course, water!
The following are some of the best low water-use plants for you to consider in your own landscape. They includes drought-resistant perennials, annuals, ground covers, shrubs, and trees.
Note: Because my home base is in Boston (USDA Zone 5), you’ll find the varieties that follow are ones I have in my own garden. They also work within a range of other USDA Plant Hardiness Zones.
Choosing Perennials for Dry Sunny Locations
You’ll find plenty of drought resistant perennials well-suited to sunny locations. I recommend incorporating a few (or even all) into your garden to lower watering requirements. It makes good sense from an ecological standpoint, too.
USDA Hardiness Zones: 3 to 9
The Yarrow (Achillea) species has flat flower heads comprised of many tiny flowers atop two- to three-foot stems and ferny foliage. Yarrow makes a great impression in big swaths.
The native perennial is carefree and white. You’ll find Yarrow naturally thriving in fields, meadows, and roadsides. Garden cultivars bloom in bright shades of yellow, gold, white, pink, and red. Beneficial bugs love carefree Yarrow—no doubt you will too.
USDA Hardiness Zones: 3 to 9
Another drought-tolerant perennial for sun is Blanket flower (Gaillardia x grandiflora). It’s multi-colored, daisy-like blooms seems to thrive upon neglect.
You’ll find even a single blossom is quite colorful, having concentric bands of color in red, yellow, orange, and maroon, depending on variety.
Butterflies love these nectar-rich, vibrant flowers, which retain their brilliance through much of the summer. Can you blame them?
USDA Hardiness Zones: 5 to 9
Russian sage (Perovskia atriplicifolia) grows 3- to 5-feet tall with long branches and sprays of tiny blue flowers. It’s airy gray-green foliage adds to its visual appeal.
These beauties thrive in poor soil and can tolerate temperature extremes in the high-desert. It’s among the most drought-tolerant perennials, adding soft spikes of color to complement any landscape design.
USDA Hardiness Zones: 4 to 9 (depending on cultivar)
Tickseed (Coreopsis lanceolata) is a drought-tolerant favorite, especially because of its extensive bloom time–almost 3 months. (Imagine, you could travel all summer without a care!)
The “Moonbeam” variety (C. verticillata) has 1-inch, butter yellow, daisy-like flowers and grows in a mound that’s about a foot-and-a-half high. “Sunburst” (C. grandiflora) are fluffy, gold, and fringed.
USDA Hardiness Zones: 4 to 9
Daylilies (Hemerocallis) adapt to almost any situation, including drought. As their name implies, they bloom with multiple trumpet-like flowers that open in succession each day. Traditionally, Daylilies have orange flowers, but you’ll find varieties showcasing every color except pure white and blue.
They look best planted in long stretches or toward the rear of perennials beds, where they sprout tall flowering stalks. Another incentive to add Daylilies to your garden is that they multiply well, year-after-year, and are relatively pest-free.
USDA Hardiness Zones: 4 to 9
Stonecrop (Sedum) is an excellent choice when considering drought-tolerant options.
The creeping variety, like the whirled, drought tolerant ground cover sedum humifusum, blossoms in June cheery yellow star-shaped flowers.
The upright variety, like the Sedum “Autumn Joy,” develops showy flower heads that turn from green to pink to red to brown as the season progresses. Even the dried seed heads add structure to the winter garden, if left intact.
Other Drought-Tolerant, Sun-Loving Perennials You Might Consider
You may want to consider these other excellent perennial choices for drought-tolerance in sunny locations, too:
- Aster (Asteraceae)
- Lavender (Lavandula)
- Blazing Star (Liatris)
Lavender preserves beautifully, offering its relaxing fragrance long after it has bloomed. Read more about how to preserve and store herbs here.
Drought Tolerant Plants for Shade
Shady spots present more of a challenge during dry spells. You can look to these groundcovers that provide the staying power to keep the garden interesting while you’re away.
USDA Hardiness Zones: 4 to 11
Bugleweed (ajuga reptans) produces 6-inch spiky purple flowers that emerge from scalloped foliage in mid to late spring. This evergreen groundcover spreads by runner to create a dense mat of foliage that turns shades of burgundy in Fall. It couldn’t be any more carefree.
USDA Hardiness Zones: 2 to 9
Lily-of-the-Valley (convallaria majalis) perfumes the air in Spring, and despite the delicate nodding stems of cupped flowers, it’s surprisingly tough. It typically flowers in white, but you can also find this drought-tolerant beauty with soft pink cups.
Once their intoxicating bloom comes to an end, Lily-of-the-Valley provides a dense green layer of foliage to sustain its value. (Plus, a handful of flower sprigs make a lovely scented bouquet!)
Periwinkle (Creeping Myrtle, Dwarf Myrtle)
USDA Hardiness Zones: 4 to 9
Creeping Myrtle (vinca minor) also does well in dry shade, with its glossy, forest green, almond-shaped foliage. In early spring, it dons a beautiful sprinking of 1-inch purple stars in blue or white. Myrtle is a tenacious drought tolerant ground cover that will grow in the most unwelcoming spaces.
In fact, it may even crowd out more delicate perennials, given the chance. It’s a reliable, drought-tolerant option that takes root where few others would survive, such as in the deep, dry shade under at the food of a swamp maple tree.
USDA Hardiness Zones: 3 to 8
Heartleaf Bergenia (Bergenia cordifolia) has leathery evergreen (heart-shaped) leaves. From them, arise ½-inch white or pink bell-shaped flowers above 2-foot stocks in late spring. It’s known for its incredible hardiness and vigor, so a little drought hardly presents an issue for this beautiful perennial.
Adding Lasting Color with Drought-Tolerant Annuals
Compliment a transient perennial display with the long-lasting color and blooms of drought tolerant annuals. You can pick from a number of alternatives to the high-maintenance “old standbys,” which tend to wither at the first sign of neglect.
USDA Hardiness Zones: 2 to 11 (Annual)
Succulent Moss Rose (Portulaca), with needle-like foliage and dainty 1-inch rosettes blooms in mixed colors, including white, yellow, pink, red, and magenta. They are a perfect drought-tolerent option for window boxes and as an accent in the front of perennial beds. You will be pleased with their on-going performance!
USDA Hardiness Zones: 3 to 9 (Annual)
A border of annual dianthus, with gray green foliage and brilliant one-inch fringed flowers are like mini-carnations. The shallow-rooted but hearty plant, also known as “pinks,” blossom in shades of white, pink, and red and. You’ll find they can really can take the heat!
Choosing Drought Tolerant Shrubs and Shrubs
Don’t overlook drought-tolerant trees and shrubs when adding structural interest to the garden that supports your travel lifestyle.
USDA Hardiness Zones: 4 to 8
You might consider an “unusual” addition to your landscape, such as the Smoke Tree (cotinus coggygria). Another drought-tolerant option, tis tree displays puffs of burgundy “smoke,” adding texture in the form of fuzzy hairs as its flowers fade. You might also appreciate its peak seasonal appeal of striking yellow or orange-red foliage in autumn.
USDA Hardiness Zones: 6 to 9 (depending on cultivar)
Scarlet Firethorn (Pyracantha) grows to 15 feet and offers a profusion of small white flowers in spring, followed by brilliant pea-sized orange-red berries. This drought-tolerant, care-free shrub looks good throughout multiple seasons. It’s especially popular with birds.
USDA Hardiness Zones: 4 to 9
Looking for something to provide landscape interest year round? Wintercreeper (euonymus fortunei) is an evergreen with stiff, sometimes variegated almond-shaped 1-inch leaves upon woody branches. Varieties range in stature from ground cover to shrub. All are drought-tolerant.
Selecting Other Drought Tolerant Shrubs
Other drought-tolerant shrubs you might want to look into include:
- Cinquefoil (Potentilla fruticosa)
- Honeysuckle (genus Lonicera)
- Blue Rug Juniper (Juniperus horizontalis)
The Most Important Thing: The First Year
Even though these plants withstand drought conditions, you will need to sufficiently water them in the first year so they establish a strong root system. So, if more traveling is in your future, now is a perfect time to establish a garden that will do well without coddling.
Planting Tips for Drought Resistant Perennials
Here are a few tricks to start your plants off right:
- Amend soil with a compost, aged manure, or other soil additives to enhance its nutritive value.
- Add natural or synthetic soil polymers, such as Tarawet ® or Soil Moist ® crystals that absorb and hold excess water until it’s needed by the plant roots.
- Plant a wet clump of long fibered sphagnum moss right in the planting hole. The moss holds water.
- Give new plantings special attention to make sure they don’t dry out during that critical first year. This will establish a strong root system and a healthy plant that can resist pests and disease.
Whether you design an entire landscape around drought tolerance or simply have hopes of your beautiful garden thriving while you’re off on a weekend road trip, breathe a sigh of relief. By adding these varieties to you’re garden, you can travel without worrying too much about watering. Who knows, it may even come to rival the world’s best botanical gardens.
