Extremely Drought Tolerant Perennials

A Starter List of Plants for the Gardener Who Doesn't Like to Water

  • 1.

    A very extensive list of perennials that, once established, will survive water shortages and perform nevertheless. Beat heat and drought with these survivalist perennials.

  • 2.

    Agastache (Anise Hyssop)

    This is one of the easiest perennials to grow; it is drought tolerant, deer resistant, and attracts butterflies and hummingbirds like crazy.

  • 3.

    Achillea (Yarrow)

    Yarrow is one of the easiest perennials to grow and is a good choice for beginners. All it needs is full sun and well-drained soil. It thrives in average to poor soil and is drought tolerant once established. Plants grown in rich soil tend to be tall and floppy.

  • 4.

    Agave

    Agaves typically flower only once every 15-25 years and the main crown dies after blooming.

  • 5.

    Allium (Ornamental Onion)

    Butterflies and honeybees adore the flowers' sweet nectar but deer and rabbits steer clear of this perennial beauty.

  • 6.

    Andropogon (Big Bluestem)

    Dubbed the “monarch of the prairie”, this native grass was once the dominant component of the American tallgrass prairie. It adapts easily to a wide range of soil and moisture conditions as long as full sun is provided. This long-lived grass has a variety of uses including screening, naturalizing, restoring prairies, and nesting materials for birds and mammals.

  • 7.

    Anthemis tinctoria (Golden Marguerite)

    Anthemis is an excellent perennial for poor soil; it may become tall and leggy if grown in rich soil. This plant is ideal for a well-drained spot in full sun. Drought tolerant once established.

  • 8.

    Arabis caucasica (Rock Cress)

    This alpine perennial is perfect for rock gardens and crevices where it will spread slowly while retaining its neat habit.

  • 9.

    Armeria maritima (Thrift, False Sea Pink)

    As its name implies, Sea Pinks are found naturally along coastlines where few other plants can handle the high salt concentration. Inland, this attribute makes them useful for planting along sidewalks or driveways that are salted in winter. They are also good candidates for rock gardens, troughs, or between pavers.

  • 10.

    Artemisia schmidtiana (Silver Mound Artemisia)

    An excellent choice for hot, dry sites, Artemisia should be grown in very well-drained soil and full sun. To avoid "melting out", it should be grown in poor soil and trimmed back in late spring to rejuvinate the foliage. This plant tends to open up in the center during hot summers, so it is best grown north of zone 7.

  • 11.

    Asclepias tuberosa (Butterfly Weed)

    Gather bouquets of Asclepias all summer long; the long stems are wonderful for cutting and are long-lasting. Sear the ends of the cut stems over a flame to stop the milky sap from leaking out. Following the fabulous flowers, green fruits develop which rupture to reveal seeds with long, silvery-white, silky hairs reminiscent of its cousin, common milkweed. These are great to use in dried flower arrangements.

  • 12.

    Baptisia (False Indigo)

    Baptisia is easy to grow and will thrive with little maintenance. There are many potential applications in the landscape including meadow plantings, as a backdrop in borders, or as a specimen. Plants are very long-lived once established.

  • 13.

    Buddleia (Butterfly Bush)

    Butterfly Bushes have certainly earned their place in the garden over the years, and its easy to see why. Just when we need a breath of fresh air in the late summer heat, they happily burst into bloom. At a time when many other plants are already spent, buddleias are just beginning their show. Their passive coloring and texture makes a wonderful backdrop for perennials, and you'll love the butterflies, bees, and hummingbirds that flock to their honey-scented blossoms.

  • 14.

    Calamagrostis acutiflora (Feather Reed Grass)

    Calamagrostis acutfilora provides a great backdrop for lower growing, flowering perennials throughout the year. It is also useful for screening purposes and will not reseed. A good choice for heavy clay soils.

  • 15.

    Cerastium tomentosum (Snow in Summer)

    The woolly texture of the leaves are a natural deterrent to unwanted critters.

  • 16.

    Coreopsis (Tickseed)

    Coreopsis is easy to grow, thriving in any well-drained soil and full sun. Once established, it is rather drought tolerant.

  • 17.

    Delosperma (Hardy Ice Plant)

    Delospermas are highly heat and drought tolerant, making it a good choice for waterwise landscapes. It thrives in rock gardens, on slopes, in containers, and in the landscape.

  • 18.

    Dianthus (Pinks)

    Dianthus can be grown in full sun or part shade, but the foliage will not be as lush and fewer flowers will be produced if it is grown in hot, dry areas. Regular watering during prolonged dry spells will be necessary. However, they are tolerant of short periods of dryness.

  • 19.

    Echinacea (Coneflower)

    Praised for their cheerful brightly colored flowers, coneflowers are a mainstay in today's garden. Be sure to leave some spent blooms on the plants in the fall because their seeds provide winter food for finches and other birds. The dried seed heads also provide architectural interest in the winter.

  • 20.

    Echinops bannaticus (Globe Thistle)

    These distinctive flowers rise above the showy silvery green foliage. Though they look prickly, they are not as rough to the touch as you might expect. Echinops makes a great cut flower or dried everlasting. They add a unique element to any arrangement and are becoming more popular with florists every year.

  • 21.

    Eryngium planum (Sea Holly)

    Looking for a perennial that will grow in that hot, sun-baked spot in your landscape? Sea Holly is just the plant! It thrives in that type of climate, and even grows in high-salt soils too (think seaside). Sea Holly is adored by florists and gardeners alike for its unique and long lasting, blue, spiny flowers which add interesting color and texture to bouquets or the garden. They are produced on intensely silver-blue stems and stand high above the basal rosette of blue-green, deeply toothed, smooth textured leaves.

  • 22.

    Euphorbia (Cushion Spurge)

    Cushion Spurge gets its name from its cushion-like, perfectly dome-shaped habit. In late spring, the pale green leaves are topped with chrome-yellow bracts that shine brightly in the garden. If sited correctly, the leaves will turn red in the fall. A good selection for northern gardens and it is extremely drought tolerant.

    Festuca glauca (Blue Fescue)

    When it comes to ornamental grasses, Blue Fescue has long been a popular choice due to its diminutive size and interesting texture.

  • 24.

    Gaillardia (Blanket Flower)

    These perennials require little care once established. They are heat tolerant and actually prefer to be grown in poorer soils. They get their name from the manner in which they used to blanket North American prairies with their blooms. They can still be found in fields and along roadsides in the prairie region and into the Rockies.

  • 25.

    Gaura lindheimeri (Wand Flower)

    Gaura is a native North American wildflower; it is very drought and heat tolerant.

  • 26.

    Gentiana cruciata (Cross Gentian)

    Gentians tend to grow best in cooler zones with mild summers. This variety is an alpine type, so it grows well in rock gardens sited in full sun to part shade. It is a durable, drought resistant plant once established. Plant it in well-drained, light soil with low to average moisture. If the soil stays wet, especially in winter, the plant may rot.

  • 27.

    Gypsophila paniculata (Baby's Breath)

    Baby's Breath has long been valued as a filler plant in perennial border gardens and also as a long-lasting cut flower. It makes the perfect cover up for dying bulb foliage or for perennials, such as poppies or bleeding hearts, that go dormant in summer. Baby's Breath also makes an excellent dried flower.

  • 28.

    Helictotrichon sempervirens (Blue Oat Grass)

    Blue Oat grass looks like a miniature water fountain, with its densely packed leaves gently spraying upward and arching back downward at the tips. This species displays spiky, blue-gray foliage that will draw your attention all season long. Blue Oat Grass adds a wonderful coarse element to rock gardens, coastal gardens, or dry hillsides.

  • 29.

    Helleborus (Lenton Rose)

    Hellebores are the harbingers of spring, blooming for six weeks or more beginning in late winter. This is the perfect plant for naturalizing in moist, woodland areas where its extensive root system will spread as far as it is allowed.

  • 30.

    Heat and drought are not a problem for this perennial. Though it is sometimes short-lived, Malva will self-seed readily assuring years of blooms.

  • 39.

    Manfreda

    Manfredas typically flower annually once they are mature and unlike Agaves, they do not die after they bloom. The bloom spike can reach 4-8ft tall with interesting burgundy brown flowers. Though this flowering performance is impressive, you'll fall in love with this plant for its fabulous foliage.

  • 40.

    Mangave

    Mangave is a relatively new phenomenon, as a cross between the genus Manfreda and Agave. These rare hybrids combine the best of both worlds: the better growth rate and the interesting patterns of Manfreda, and the habit and refinement of Agave. We are very excited (shall we say mad?) about our new hybrids from Walters Gardens, Inc. hybridizing. Growers will appreciate the fast growth rate of Mangave-these hybrids finish more quickly than Agave, thanks to their Manfreda parentage.

  • 41.

    Nepeta faassenii (Catmint)

    Nepetas are easy to grow perennials that provide a beautiful show of color all summer long. They prefer to be planted in full sun and ordinary, well-drained soil. When Nepeta's stems are broken, they release an aroma into the air that tends to attract cats, thus its common name, Catmint.

  • 42.

    Paeonia (Peony)

    Peonies are classic garden plants that add a bit of nostalgia and charm to the garden. Their fragrant blooms and lush foliage have made them popular for years, and with the recent resurgence in breeding, they will continue to improve.

By choosing a mixture of early, midseason, and late blooming varieties, you can have blooms for up to 6 weeks.

  • 43.

    Panicum virgatum (Switch grass)

    Switch grass gets its name from the peaceful swishing sound it makes when blowing in the wind. All parts of this grass are very sturdy, and will remain standing thru winter unless snows are heavy. This provides important cover for birds during the coldest days of winter. This grass is very versitile from a design standpoint; it is effective as a specimen, in masses, for screening, alongside ponds or streams, or even in large containers.

  • 44.

    Penstemon (Beardtongue)

    Penstemons should be grown in full sun and very well-drained soil. Use Penstemons in the border, for naturalizing, and for cut flowers.

  • 45.

    Perovskia atriplicifolia (Russian Sage)

    The ideal plant for hot, dry climates! Russian Sage is classified as a subshrub or woody perennial. It performs very well in full sun and any well-drained soil. Average to dry moisture levels are ideal, and few pests bother this plant. If pruning is necessary, do so in Spring when new growth appears. Prune back to just above the lowest bud.

  • 46.

    Saponaria ocymoides (Rock Soapwort)

    Saponaria is a sprawling plant which forms a nice carpet of semi-evergreen foliage. Small sprays of pink flowers appear prolifically in early summer. It works well in a rock garden, as a groundcover, or between stepping stones on a path. The common name, Soapwort, refers to the sap from the roots of S. officinalis which was once used to make soap.

  • 47.

    Schizachyrium scoparium (Little Bluestem)

    Schizachyrium is a great choice if you are looking to restore an eroded site, or for a plant that will grow in hot, dry areas where other plants have a hard time surviving.

  • 48.

    Sedum (Stonecrop)

    Tall, upright sedums form substantial clumps of foliage which can be substituted for shrubs in the landscape. Their stout, sturdy stems support the massive flower heads which develop in summer and burst into bloom in fall. If left standing, they provide winter interest and food for birds.

  • 49.

    Sempervivum (Hen & Chicks)

    Sempervivum is comprised of one large rosette called the "hen" which sprouts many smaller rosettes around it called "chicks". As the plants age, the "hen" may die out and be replaced by the "chicks". Plants can be divided easily at any time by pulling up some of the "chicks" and replanting them elsewhere. This plant is particularly effective when planted in the cracks and crevices of stone walls or walkways. It is also very attractive in containers.

  • 50.

    Sporobolus heterolepsis (Prairie Dropseed)

    This grass is very heat and drought tolerant because it is deep rooted. It is often planted en masse as a groundcover or as a specimen. Prairie Dropseed is native to North American prairies and occurs naturally from Canada to Texas. Much of it has been destroyed by overgrazing and farming, so now it is only found in undisturbed prairies. Native Americans once used its seeds to make flour. This plant gets its name from the way the tiny mature seeds drop to the ground in the fall. Birds and other wildlife depend on this plant as a nutritious food source.

  • 51.

    Stokesia (Stokes' Aster)

    Stokesia is a native North American wildflower. It has been grown for many years for its beautiful flowers and ease of culture. Because of its heat tolerance, it is widely grown in the south.

  • 52.

    Thymus praecox (Creeping Thyme)

    Creeping thyme is native to hot, dry Mediterranean regions. Consequently it thrives in similar conditions in American gardens. Plant it in full sun and moderately fertile, average to dry, well-drained soil.

  • 53.

    Vernonia (Ironweed)

    Vernonia, or Ironweed, is not commonly offered in the perennial trade, but it is a native perennial worth noting. Grows best in dry soil. Although it can handle brief periods of moisture, this plant requires well-drained soil to thrive.

  • 54.

    Yucca (Adam's Needle)

    The flowers may not be deer resistant, but the foliage definitely is. Most people like to enjoy this as a foliage interest in their garden anyway.
