Sandy soil is soil where a majority of particles are large, from .05 mm to 2 mm in diameter, that drains quickly but holds nutrients poorly. Sandy soil can have differing combinations of clay, sand and silt, but the major percentage of particles is sand.
Scarlet globemallow is a welcome addition to any xeric or High Desert garden. Small coral flowers bloom from May (sometimes April) through into the fall. Although scarlet globemallow will survive with no additional moisture in our climate, once a month watering insures steady blooms. The plant is similar in appearance to S. ambigua, which can bloom coral, white, lavender and pink.
Agastaches are some of the Southwest's showiest natives and one of our native perennials where must breeding and hybridization is being done. Native to slightly higher elevations that 3600 ft., it requires either afternoon shade or medium water-use. It has not been reliable in coming back for me, but it has for others. Well drained soil is a must. Nonetheless, it is easy to be seduced by its masses of blooms and alluring fragrances. Hummingbirds certainly are entranced.
Virginia creeper, one of our pernicious native creepers, is a worthy low care vine for brilliant fall foliage and deep blue berries (highly toxic to humans) loved by birds. Virginia creeper normally spread by seeds in bird droppings, which is the method it came to my landscape. When spotted early, Virginia creeper easily pulls out, but if not spotted, within no time, it will cover a fence, climb a pole or cover an area. Which can be either a good thing or a bad thing, depending on one's view.
Littleleaf mountain mahogany is the shortest of the mountain mahoganies usually sold. Small, narrow, leathery looking evergreen leaves on many intricate branches. Small yellow flowers in springtime and feathery seed plumes in the fall. The shrub is densely branched and slow growing.

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.
Echinacea angustifolia is the herbal echinacea. Native throughout most of the Midwest, and the Texas Panhandle. Very drought tolerant. It can be seen growing along roadsides and in nature generally. A good cut flower. The common name Black Samson refers to its roots. Not as showy as E. purpurea and newer introductions.
A Plant Select Plant for 2004, Pink Texas Skullcap has often been listed as a Zone 7 plant, but it is reliably cold hardy in Zone 6 and in protected Zone 5b sights. I’ve grown it in my xeristrip since 2000. Long blooming with no maintenance ever performed. These low growing, mounding skullcaps are excellent for Panhandle xeristrips and rock gardens. Native varieties are S. drummondii, and S. resinosa. The hybrid cultivar, S. x ‘Violet Cloud’, introduced by High Country Gardens, is an excellent violet skullcap as well as the natives.
Desert globemallow is one of those native plants that keeps on giving, asking so little in return and is a worthy addition to any native or xeric garden.

Big Bend silverleaf is the most cold hardy of the Leucophyllums and has wintered over in Amarillo, Zone 7, for 5 years so far. Possibly cold hardy to Zone 6. It is hard to beat a more attractive summer blooming shrub for small xeric spaces. After summer rainfalls, Big Bend silverleaf, native to the Big Bend National Park area, becomes covered in silver blue flowers that twinkle like jewels among its silvery gray leaves. Hard to find, it's worth searching for.
Texas, or scarlet sage is a perennial to the Southern U.S. and Texas. In the Texas Panhandle, it is sold as a bedding plant, since it is not cold hardy. Some varieties will come back due to re-seeding. Many varieties are available, some are more drought tolerant than others, such as 'Forest Fire', while 'Lady in Red' requires medium water-use beds. Summer long blooming, choose your color among scarlet, red, rose, pink, coral and white. As with most sages, hummingbirds, butterflies and bees are attracted to them.
Curl leaf mountain mahogany is a medium height evergreen shrub native to elevations between 5000-10,000 feet throughout the Southwest. Small oval shaped dark green leaves lightly curl under at the margins are evergreen and aromatic.

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.
Linum lewisii, the southwestern and western native perennial wildflower variety of flax was named after Meriwether Lewis, who was first to describe it during the Lewis and Clark Expedition. On July 18th, 1805, near the Great Falls of the Missouri Lewis recorded: "I have observed for several days a species of the flax growing in the river bottoms the leaf stem and pericarp of which resembles the common flax cultivated in the U'States. The stem rises to the hight of about 2 1/2 or 3 feet high; as many as 8 or ten of which proceeds from the same root.
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.
Dasylirion is one of the plants I call a southwest evergreen. Different in appearance from traditional evergreen shrubs, it fulfills the same purpose in native and xeric landscapes. Symmetrical rosette of narrow leaf blades or leaves emanating from the center of the rosette. Barbs lining the margins of the thick pale green leaves give Dasylirion another common name, sawtooth yucca. As Sotol ages, a trunk may form under the rosette and even multiple heads may develop. At maturity, an 8-10 foot tall flower spike ascends from the center where thousands of small creamy white flowers open.
Agaves are striking and architectural Southwest native plants and are included in a group of plants I term Southwest evergreens. They are unusual in that at maturity, they only flower once, and then die. for this reason, some classify them as multiannual, rather than perennial. However, as they common name suggests, it takes many years before they flower. Leaves of the Agave are arranged in a spiral beginning from a near invisible stem, forming a rosette.Agaves vary in size from 4-6 inches to larger than man-size.
Purple or desert sage prefers leaner, quick draining soils. It is said to grow 2-3 feet tall and deeply branched with silver gray foliage and a profusion of violet bluish flowers atop spikes in late spring and summer. Low water-use, but does better with once a month irrigation. One of the finest flowers of the desert, it is the sage of Riders of the Purple Sage, by Zane Grey. Grows throughout the Great Basin Desert.
Mountain mahogany is native to the Texas Panhandle and throughout the Southwest, found in elevations from 3000-9500 ft. Another common name is Alderleaf mountain mahogany, because its leaves resemble that of an alder. Mountain mahogany, whose wood is very hard (Palo Duro) is found in Palo Duro Canyon. Extremely drought tolerant, it will survive on 10 inches of rainfall. An aromatic shrub with shredding reddish bark, but can grow to tree size. Mountain mahogany's flowers are small, rayless and insignificant, as they are in the other species.
Bush morning glory is a non-vining herbaceous perennial with a deep taproot, allowing it to be drought tolerant, but difficult to transplant. Arching branches with narrow upright green leaves emerge from the taproot. Summer blooming with 3 inch pink to purple funnel shaped flowers that open in the morning and close in the afternoon. Bush morning glory typically inhabits sandy and sandy loan plains, meadows, prairies and roadsides.
A great plant for those people who must have their foliage fix. Despite their large foliage, cannas will do quite well in a medium water-use area with well amended soil.There are dwarf varieties and others that will reach 7 feet. Leaves shred easily by hail, but will recover after several weeks. Cannas sprout from thick rhizomes. Although subtropical, cannas easily winter over in the Texas Panhandle and spread to form a thick root mass.
A mid height grass suitable for any low water-use garden, city or country. It does self-seed somewhat, but I hadn’t noticed it to be a problem in a xeric setting (simply remove or transplant them). It's greatest attribute is it's gently flowing nature int he wind. It is native to Texas and the southwest. I saw it growing along the slopes of the Chisos Mountains in Big Bend National Park. It pairs well with yucca, agave, Calylophus and any native shrub.
If I had to pick my favorite plant, this is it. Long blooming and drought tolerant with only minimal maintenance of late winter cutting back, and maybe a bloom pick-me-up deadheading at mid summer. It will also re seed some so you’ll have more of them the next year. It’s fragrance is light and pleasantly of sage. Salvia greggiis are native to Texas in the Kerrville area. It is my favorite, but not the absolutely perfect plant. The stems are quite brittle and very easily break or snap off, even when you’re carefully weeding around it.
Desert marigolds are one of the prettiest desert flowers. The plant forms a neat compact rosette of finely cut silvery green leaves from which stems emerge topped with a bright golden daisy like flower. It is considered either an annual or short lived perennial. Scatter seeds from the spent plant to insure its return the next season. Over watering will doom this beautiful plant. Desert marigold can be seen blooming in the desert in winter and spring. In my garden, it's blooms begin in May and will continue sporadically into fall. Not awfully reliable in cold hardiness here.
