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:

1. Planning and Design
2. Soil Improvement
3. Limited Turf Area
4. Efficient Irrigation
5. Mulching
6. Low Water-Use Plants
7. 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) of these perennial plants into your garden to lower watering requirements. You’ll save money on your water bill and still enjoy colorful blooms in the summer months. Some have the extra bonus of making a great cut flower, too!

And it goes without saying that It makes good sense from an ecological standpoint, too, given climate change.

Here is a short list of drought-tolerant perennials you can rely on to look their best, despite dry conditions and summer heat.

1. Yarrow

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. Not only is it drought-tolerant, but it’s also deer resistant. 

This native perennial of North America, Europe and Asia is carefree and white. 

You’ll find the Achillea millefolium 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!

2. Blanket Flowers

USDA Hardiness Zones‎: ‎3 to 9

Another drought-tolerant perennial for sun is Blanket flower (Gaillardia x grandiflora). Its multi-colored, daisy-like blooms seems to thrive upon neglect, blooming in early summer to late summer.

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?

3. Russian Sage

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. 

In fact, it’s among the most drought-tolerant perennials. It adds soft flower spikes of color to complement any landscape design. 

4. Coreopsis

USDA Hardiness Zones‎: ‎4 to 9 (depending on cultivar)

Tickseed (Coreopsis lanceolata) is a drought-tolerant favorite. That’s because of its extensive bloom time–almost 3 months. (Imagine, you could travel all summer without a care!) 

Better yet, they’re one of the easiest perennials to grow in your garden beds.

Usually, the flowers of this beautiful plant are different shades of yellow. For instance, the “Moonbeam” variety (C. verticillata) has 1-inch, butter yellow, daisy-like flowers. It grows in a mound that’s about a foot-and-a-half high.

“Sunburst” (C. grandiflora) are fluffy, gold, and fringed.

You’ll find lots of Coreopsis varieties to choose from at the nursery. None will disappoint.

5. Daylily

USDA Hardiness Zones‎: ‎4 to 9

Daylilies (Hemerocallis) adapt to almost any situation, including drought. As their common name implies, they bloom with multiple trumpet-like flowers that open in succession each day. 

Traditionally, Daylilies have orange flowers at the top of their long stems. Gardeners sometimes common variety “ditch lilies” because they are so easy to cultivate. They tolerate less than ideal conditions, even sandy soil and partial shade.

But they are not limited to orange flowers. You’ll find varieties showcasing all different colors–except pure white and blue. Some even have brilliant red flowers – that’s a real showstopper you can plant along a rock wall in part shade or in full sun.

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. Once established, they are a reliable drought-resistant perennial that will bloom and multiply for year.

They are edible, too. Several asian specialties feature daylily flowers in the dish. You can also add them to your salad. Humans and dogs can safely consume all parts of the daylily, but they are not safe for cats to eat.

6. Stonecrop

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 with cheery yellow star-shaped flowers. 

The upright variety, like the Sedum “Autumn Joy,” develops taller showy flower heads with pink flowers. You’ll enjoy seeing the crown turn from green to pink to red to brown as the season progresses. And the succulent gray-green leaves add a nice textural element to the flower garden. This is one of the drought resistant perennials that belongs in every garden.

Even the dried seed heads add structure to the winter garden, if left intact. 

Other Sun-Loving, Drought Resistant Perennials You Might Consider

You may want to consider these other excellent perennial choices for drought-tolerance in sunny locations, too:

• 7. Aster (Asteraceae)
• 8. Lavender (Lavandula)
• 9. Blazing Star (Liatris)
• 10. Purple Coneflower (Echinacea purpurea)
• 11. Black-eyed Susans (Rudbeckia)
• 12. Globe Thistle (Echinops)
• 13. Butterfly weed (Asclepias tuberosa)

Lavender preserves beautifully, offering its relaxing fragrance long after it has bloomed. It’s no wonder these fragrant flowers are such a favorite in the herb garden! Read more about how to preserve and store herbs here.

5 Drought Tolerant Plants for Shade

Shady spots present more of a challenge during dry spells. You can look to these ground covers that provide the staying power to keep the garden interesting while you’re away. 

Here are some other drought resistant perennials for shade.

1. Bugleweed

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 ground cover spreads by runner to create a dense mat of foliage that turns shades of burgundy in Fall. 

It’s a great choice for a dry garden, and really couldn’t be any more carefree. It will multiply, so you’ll want to keep it in check.

2. Lily-of-the-Valley

USDA Hardiness Zones‎: ‎2 to 9

Lily-of-the-Valley (convallaria majalis) perfumes the air in Spring. Despite the delicate nodding stems of cupped flowers, it’s surprisingly tough. 

This old-fashioned garden favorite typically flowers in white. But you can also find this drought-tolerant beauty with soft pink cups. Lily-of-the-Valley also have a rather long bloom period, for 3-4 weeks in early- to mid-spring. 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!

3. 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 sprinkling 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. It’s a perfect solution to the deep, dry shade under at the food of a swamp maple tree. 

4. Bergenia

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. 

This lovely plant is known for its incredible hardiness and vigor. So, a little drought and dry soil hardly present an issue for this beautiful perennial.

5. Ornamental Grasses in Light Shade

Another good option for shade are ornamental grasses. Most, such as Blue Fescue, prefer a sunny spot. But you can look to a few ornamental grasses, like Luzula nivea, Hakonechloa, Anemanthele and Deschampsia that will do well in light shade without much water.

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. 

1. Moss Rose

USDA Hardiness Zones‎: ‎2 to 11 (Annual)

Succulent Moss Rose (Portulaca) has needle-like foliage and dainty 1-inch rosettes blooms in mixed vibrant colors. You’ll find them blooming white, yellow, pink, red, and magenta. 

These beautiful flowers are a perfect drought-tolerant option for your window boxes and in the rock garden. Their succulent leaves indicate that they can better tolerate dry summers. They also make a great accent in the front of other drought-tolerant flowers in your perennial beds. 

You will be pleased with their on-going performance! 

2. Dianthus (“Pinks”)

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 plants are also known as “pinks.” 

They blossom in shades of white, pink, and red and. You’ll find they can really can take the heat! Plus, they make a great border plant.

3. Shade Tolerant, Low-Water Plants

To compliment your drought tolerant flowering annuals, mix in some sweet potato vines, which can tolerate high heat and periods of drought. You’ll want to make sure they have enough water to thrive, but will have peace of mind if you are out of town or simply want to use less water.

Choosing Drought Tolerant Shrubs and Trees

Don’t overlook these 7 drought-tolerant trees and shrubs when adding structural interest to the garden that supports your travel lifestyle.

1. Smoke Tree

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, this tree displays puffs of burgundy “smoke.”  Smoke Trees add 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.

2. Scarlet Firethorn

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. That’s followed by brilliant pea-sized orange-red berries in early fall, as the fruit matures. 

This drought-tolerant, care-free evergreen shrub looks good throughout multiple seasons. Of course, it’s especially popular with birds, too.

3. Wintercreeper

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.

4. Selecting Other Drought Tolerant Shrubs

Other drought-tolerant shrubs you might want to look into include:

• 5. Cinquefoil (Potentilla fruticosa) 
• 6. Honeysuckle (genus Lonicera)
• 7. Blue Rug Juniper (Juniperus horizontalis)

The Most Important Thing About Drought Resistant Perennials: The First Year

Even though these drought resistant perennials and plants can withstand drought conditions, you will need to sufficiently water them in the first year. That way,  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. These 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 also 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.

Final Thoughts on Drought Resistant Perennials

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, you can breathe a sigh of relief. 

By adding these varieties to your garden, you can travel without worrying too much about watering.

From the scorching temperatures in dry climates to unpredictably hot summers in your New England rock gardens, incorporating these plants in your flower beds is a great way to handle a dry spell. A little water can go a long way, and provide you with a variety of colors to responsibly beautify your landscape.

Who knows, it may even come to rival the world’s best botanical gardens!
