Plants that are native to the American Southwest that exist without supplemental irrigation once established.
Junipers are native to much of the U.S. and come in many sizes and shapes. Juniperus horizontalis is the low growing and spreading juniper, used mainly as an evergreen groundcover. There are many varieties available, one or more to suit every purpose and location. Colors and heights vary from the common dark green evergreen to blue green, blue and even lime or chartruese. Their hallmark is their fine texture, many of the newer varieties have a pleasant soft touch. Water use can vary as well, but typically, once established many will thrive on once a month deep watering.
Texas beargrass is a grass-like perennial evergreen plant native in rocky and limestone soils from central Texas to the upper Rio Grande Plains and west to the Trans-Pecos and into S.E. Arizona. Not a true grass, Texas sacahuista is a member of the lily (Liliaceae ) family. It flowers in Amarillo in early April. A short flowering stem barely rises above the many thin leaves. The flowers appear rose or reddish on the outside before opening, are numerous, white to cream colored forming dense vertical clusters.
Drought tolerant perennial with white cup shaped blooms usually found growing in poor soils. I planted it in heavily amended soil, and I think it was too rich for it. It was eaten up during the heat of the summer by flea beetles. I thought the too rich soil was the cause; however, Judith Phillips in Plants For Natural Gardens, wrote about this same occurrence in native soils. Phillips hypothesized this may be a way for tufted evening primrose to escape summer’s heat. However, my plant died, rather than just going to ground.
Native evergreen shrub that makes an excellent hedge plant and wind break. Its blue-green prickly leaves keep the unwanted out (to a point). Please allow room for its spread.
A habitat plant for shelter and as a food source of food for birds and other wildlife that is an attractive addition to the home landscape, where an evergreen shrub is called for in a sunny spot. Sun yellow flowers in March. Cold hardy to -20°, algerita can be found growing from 4000 to 7000 ft. in elevation in Texas, the southwest and Mexico.
Sumacs are known for brillian fall foliage. Ground cover woody shrub 24-30" tall with dark shiny green leaves that turn a thrilling orange-red in the fall. Small yellow flowers at springtime.
Perennial vine native to the Southwest. Late summer to fall bloom with slender, thin whitish sepals, followed by attractive plumes that are feathery seed clusters. The vine is valued for it's delicate beauty of leaf, flower and plume and drought tolerance. Clematis drummondii is a larval host and/or nectar source for the fatal metalmark butterfly.
Buffalograss is North America's only native turfgrass, grows well in clay soils. A warm season grass that spreads by stolons, it is our best selection for low water-use lawns. It will survive very nicely on 15-20 inches of annual precipitation. For green turf summer long, a once a month watering is all that is needed. The common species is short to 4-8 inches, light gray/green to blue/green and goes dormant in fall, greening up again in May. Many newer varieties are being developed for wider blades and deeper green colors, such as Legacy® and Turffalo®.
One-seed juniper is the juniper found in the dry hills and mesas throughout our area and the Southwest in elevations from 3500 to 8000'. Slow growing on top, it's tap root grows quickly and deeply, making them very difficult to transplant. It's habit is shrubby with several stems and branches growing low to the ground, making it a good habitat plant. Extremely drought, heat and cold tolerant.
Oenothera macrocarpa, and O. missouriensis have been used interchangeably. Native over a wide range including the plains and wooded areas, carries the common name, Missouri evening primrose, bigfruit sundrops and Ozark Sundrops.
Veronica x ‘Blue Reflection’ should be an indispensable evergreen groundcover for you, as it has become for me.
Summer flowering low water-use native tree, several varieties to choose from. Willow like green leaves. Cold hardy reliably in Zone 7, will winter over most years in Zone 6. The variety pictured in the close-up flower photo is "Lucrecia Hamilton", the variety in the third photo is 'Art's Seedless'.

Will grow in clay and poorer soils. Very pleasing wispy, arching habit with a soft sway and rustle in the wind. Can grow in partial shade. Seed heads are somewhat purple, fine textured. Will reseed. Low or no water-use.
Winterfat, formerly Ceratoides lanata, is a drought and heat tolerant that normally is found in poor, alkaline soils throughout the Southwest in grasslands and scrublands. Winterfat is a low rounded woody shrub with pale blue green to gray leaves. The distinctive characteristic is the long wooly seed stalk it puts up in the summer. Towards winter, the stalk appears to be covered with wool.
Artemisia versicolor 'Sea Foam' is mostly grown for its gray foliage. To keep it's desired compact shape, cut off flower stalks after blooming, which is its only maintenance. Soft, rubber-like feel to its short, clustered, needle-like appearance on short 1 inch wide columns. It gives the impression of a coral bed in your rock garden. Not invasive. 2004 Plant Select Plant.
Gorgeous! Luscious goblet shaped lemon yellow flowers on this native wildflower that also develops elongated seed capsules. The lighter, silvery sheen of the leaves distinguishes the O. macrocarpa var. incana subspecies, and is also an evening to morning bloomer.
Not our old fashioned garden zinnia. Zinnia grandiflora is the native zinnia for most of the Midwest, West and Southwestern parts of the United States. So widespread a wildflower, each region has named it theirs: plains zinnia, prairie zinnia, desert zinnia and Rocky Mountain zinnia. A terrific low growing and spreading groundcover for poor soils needing no supplement irrigation. Rugged! A survivor without being a pest!
Small but tough is Perky Sue. Woody base with thin short green leaves from which many stems shoot up to display many yellow daisy like flowers from April into fall. Many people know this plant by the genus name Hymenoxys, but has been changed to Tetraneuris in the last decade. There are a few relatives that look quite similar and are all equally valuable in the garden: T. acaulis and T. odorata.
Broom snakeweed is a small mounded subshrub with yellow greenish thread-like leaves, native throughout the Southwest and western half of the North American continent. In the fall, it becomes covered in small golden yellow flowers. Bees and nectar butterflies are attracted to it in numbers. Usually grows to only a foot tall.
Lindheimers muhly grass is native to the Edwards Plateau of Texas. It is cold hardy and heat tolerant, a tall, warm season bunch grass. It forms a good size ornamental specimen with upright blue green or blue gray blades and tall showy, almost spike like inflorescences in late summer. Not as large as pampas grass, it is a better native alternative. There are two muhly grasses native to the Southwest, Muhlenbergia asperifolia, scratchgrass, and M.
Lavender cotton, or gray santolina is a low mounding woody subshrub that should live on the lean side. Not that it won't overgrow if fed. It will maintain its compact shape in poorer soils without amending or fertilizing. Small silver gray leaves cover the shrub. Tiny yellow button flowers appear in summer. Evergreen, the santolinas are native to the Mediterranean area. Aromatic and edible, it's leaves were used as a flavoring in broths, sauces and grain dishes. Low water-use.
Native to the Texas Panhandle, the south and into northern Mexico. Strong chocolate scent fills the morning air. Xeric herbaceous perennial with a deep taproot. Flower closes up during the heat of the day, staying open during more moderate days. Good choice for naturalizing. Best to keep soil on the lean side, will grow leggy in amended soil. Reseeding profusely. Cut back flower to base at end of June if it becomes too leggy. Within weeks, it'll grow back and begin flowering again.
Russian sage is a must have shrub for every low water-use landscape. Russian sage is used extensively throughout our southwest landscapes, planted along with Buddleia, Carl Forester Reed Grass, Salvia greggii cultivars, Anisacanthus quadrifidis wrightii and Hesperaloe parviflora. It is hard to beat its use where a long flowering, showy, low care, drought tolerant shrub is needed.
Lower growing Southwestern native shrub, both cold and heat tolerant. Finely cut greenish silver leaves. Flower stalks with insignificant flowers. Grows best in soils with good drainage. Will grow in heavy clay soil if grown among grasses.
Warm season native clumping ornamental grass that is well suited to the transition zone between turf and flower bed. Medium to blueish green thin grass blades form a low to medium size clump, medium water-use zone. In late September, it sends plumes upward that give the appearance of a deep pink haze or mist. There are several new selections of Gulf Coast muhly, thankfully, to choose from. Be sure to pay attention to the cold hardiness for your area and you won't be disappointed.
