Plants that are native to the American Southwest that exist without supplemental irrigation once established.
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.
Tansy aster is an annual native to the Southwest and throughout the Plains even into Canada. Fernlike, or tansy-like (tannacetifolia) light green foliage with beautiful aster-like lavender flowers with yellow disks about 1 1/2 to 2 inches across. Blooms from late spring through fall. A once a month watering will keep the blooms coming throughout the summer. It will keep its compact shape in lean, poor soil but will become much larger in well amended soil. Minimal amending is recommended. Tansy aster is another example of our natives plants giving so much, asking so little in return.
Switchgrass is one of the best native ornamental grasses of our tall prairies. Switchgrass forms upright bunches of wide 1/2 inch green blades, with open pale purple inflorescence arising another 2 feet in late summer to fall. Switchgrass will thrive with every other week supplemental irrigation. There are many varieties of switchgrass, 'Prairie Sky' is the most drought tolerant (low, xeric) with blue blades. Other fine selections are 'Heavy Metal' with metallic lavender blue foliage turning reddish towards fall, and 'Shenandoah' with leaf blades tipped in red.

Desert never equates with drab. The flowers on Desert Bird of Paradise are simply stunning! Though classified as a Zone 7 plant, I’ve grown Desert Bird of Paradise for 3-4 years near a south facing wall and have seen several others around Amarillo, without it dying back it to roots. However, if it does, just prune out the dead wood. Eye catching flowers bloom continually from June into fall and attract hummingbirds. Finely divided green leaves. It is said to survive on 8” of rainfall, but monthly soakings enhance it. C. mexicana, Mexican Bird of Paradise and C.
Salvia argentea is a first class drought tolerant biennial to add texture to your xeristrip. Light gray green tomentose (hairy) foliage adds contrast against accent rocks. This biennial will flower the second year, but I could do without the sticky, and somewhat unsightly stalk whose white flowers open in succession and quickly turn brown. Cutting off the stalks only encourages the plant to send up more sticky stalks. The leaves of the plant may appear to mimic Lamb’s Ears, however, they are not tough and resilient, tears easily, and are shredded by hail.
Black dalea, an autumn blooming southwest native shrub, should be used more in the home xeric landscape. Growing only to about 3 feet, black dalea spreads out with thin, wiry branches and small, green, compound leaves. The shrub becomes completely covered with tiny purple flowers as to be enshrouded in a purple cloud.
Many references are unsure of its cold hardiness to zero, and it had thrived nicely in my city garden in Amarillo. However, it does not seem to be reliably cold hardy. It's a beautiful shrub that provides stunning late fall color that is worth replanting.
You can't have just one. As soon as you plant one, you'll have a drift, then a sweep, then a field if you have the space. But I still don't consider the prairie coneflower to be invasive, merely pleasant. Next to the Indian Blanket, the Mexican Hat shouts Southwest prairies. And its a tough hombre.

Coneflowers bloom yellow, reddish or brown late spring into fall and make an attractive display when mixed.
Bigelow's tansyaster is easy to confuse with Tahoka daisy but is not as showy. Bigelow's aster is a fall blooming biennial, with far fewer purple rays and a smaller, yellow brown center disk. It populates plains in Colorado, Arizona and New Mexico. In the fall, whole fields will wear a purple haze due to this tansyaster.
Alkali sacaton is a perennial warm season bunch grass native to the Southwest. In late summer to fall, airy triangular seed heads wave above the silver green grass blades. Grows in alkali soils, many say in locations where there is moisture nearby, prefering heavy clay soils. It is quite drought tolerant once established, and long lived. It will, of course, grow bigger or smaller depending on water resources.
Littleleaf mockorange is native throughout the foothills, dry rocky slopes and open woodlands from 4000 to 8000' in the Southwest usually growing to only 4 feet.

Please notice the beautiful deeply, palmately lobed green leaves, similar to geraniums. Callirhoe involucrata makes a good drought tolerant ground cover, however, it is not evergreen. The cup shaped flowers are usually rose or magenta, however, native plants may exhibit lighter colors. As temperatures rise above 90 - 95 degrees, flowering will stop until temperatures cool. A Plant Select Plant. Give this plant plenty of room as it smothers plants it grows over. C. involucrata 'Logan Calhoun' is a white flowering poppy mallow. C. involucrata v.
Our native skullcap is one that should be included in every drought tolerant landscape, short lived though it is. This is the kind of garden-worthy plant we all desire, neat, compact and all season blooming with no maintenance to speak of. You just can't go wrong as long as your soil has decent drainage. It reseeds some, but to me, this is just a bonus.
If you find yourself in Palo Duro Canyon at the end of April or beginning of May, the purple haze dotting the cliffsides is feather dalea. Sporadic blooms will open after showers throughout summer, though never as profuse as in springtime. With monthly irrigation in a xeric garden, feather dalea adds color and texture with it's twiggy, but sturdy, appearance. Small purple flowers combined with white plumes carries the haze impression from a distance.
Another tough and pretty wildflower that populates a wide area from the plains of Oklahoma down to the Chihuahua Desert and over to Colorado and Utah. Leaves are lower near the base of the plant from which stems emerge and bloom in late spring to early summer. Yellow rays with a red to brownish center.
Rounded mounds of green leaves on multi-forked stems put forth multitudes of fragrant purple/magenta flowers from summer into autumn. Flowers open in late afternoon (perhaps around four o'clock) and close in early morning. Cold hardy and heat and drought tolerant, after freezing in the fall, the top growth breaks away. Desert four o'clock emerges in the spring from a large root. Will not transplant well once established. Southwest native perennial is usually found in somewhat shaded areas.
Giant sacaton is one of the largest bunch grasses native to the Southwest, like alkali sacaton on steroids. Seems to thrive in poor soils with no supplemental irrigation. It will grow even bigger with added moisture. Thick textured grass blades, it will rival pampas grass for size and beauty, although it plumes are near as showy, giant sacaton has a flowing fountain appearance. A warm season grass, it is cold hardy and thrives in sun and heat.
Gambrel oak is a common native oak species throughout the Rocky Mountain foothills and here in the Texas Panhandle as well. Often times it grows more to a tall shrub, with sufficient moisture it can mature into a small tree. Beautiful somewhat glossy lobed green leaves to 3-5 inches long. Beautiful fall foliage. Will put out a profuse amount of acorns. Gambrel oak can form a thicket. Cold, heat and drought tolerant. Inconspicous tiny red flowers appear shortly after leafing and are normally hid by the leaves.
This native shrub should be used alot more in our area. Drought tolerant shrub. If planted in a moister area it is important to have good drainage. Attractive and pleasantly fragrant fern-like foliage. The tiny white flowers with yellow centers that appear towards the end of the branches in June should be clipped in fall to late winter for better appearance. It is said the deer do not browse fernbush. Semi evergreen, it does loose its leaves in Amarillo. Reputed to be cold hardy to -25°.
A non-invasive tansy from southern and central Europe for your low water-use bed and border that will reseed somewhat. A short lived perennial. Gray cut-leaf foliage provides an attractive white element in the garden.
Dark green, semi-evergreen aromatic leaves are the feature most prized, along with the tiny yellow daisy-like flowers that bloom spring to fall. Damianita prefers full sun and lean soil and does well in heat and temperatures to zero degrees. Daminaita will lose its leaves in cold winters.
Mexican blue sage is a native of Mexico and in many references labels it cold hardy to USDA Zone 8, however, it has wintered over in Amarillo many years now, even in full northern exposure. It has died back to the ground once or twice, but comes back up from the roots. If good to well drained soil is provided, it should do fine. And I hope you can provide that, as Mexican blue sage is one of my top plants to include in xeric gardens. True bright blue flowers bloom summer and fall with once a month watering. Butterflies are attracted to it. Indispensable.
