Caliche is defined as a crust or a succession of crusts of calcium carbonate that form within or on top of stony soil in arid and semi-arid regions and is often combined with clay. Caliche is lacking in organic matter. Its crusting tendencies often prohibit drainage.
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.
The Calylophus genus is one of the best Southwest native plants for Panhandle gardens. Heat and drought tolerant, long blooming with little to no care, what garden would be without it? Sunny yellow 4 petaled sundrop flowers bloom in an explosion in spring, and respectably during the remaining growing season, especially when given a once a month inch of water during drought conditions. Each individual flower lasts only a day, tight compact mounds sport the orange spent blooms as well as the new bright yellow flower.
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.
White flowering zinnia is native to the Southwest and Northern Mexico. A low mounding plant, it becomes completely covered with small white flowers with a central yellow disk, similar to our native prairie zinnia, Zinnia grandiflora. Blooms from June through fall. Desert zinnia is toxic if ingested by humans.
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.

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.
Yuccas for Texas High Plains Landscapes
Previously known as Cowenia mexicana, it is known today as Purshia stansburyana, also, P. stansburyiana. It is still commonly called a cliffrose. The cliffrose blooms prolifically in May with creamy white to pale yellow fragrant flowers that continue blooming for several weeks. Semi evergreen, it loses it's leaves in colder winters. Upright stems and branches can appear unruly in its growth pattern; small dark green resinous leaves.
Illinois bundleflower should be grown for its unusual characteristics of seedpods and leaves, if nothing else. A member of the legume or bean family, the seed pods turn dark brown, leathery and twisted in appearance and rattle in the wind in late fall. The compound, alternate, pinnate leaves fold when touched or when exposed to strong sunlight. Small white flowers in summer. Attracts butterflies, birds love its seeds. The plant can grow to be quite large if in high water-use areas.
Blue grama grass is a short, clumping warm season grass with thin blue green blades that is native throughout the Great Plains and Southwest. Able to grow in poor, dry soils, blue grama grass needs only about 12 inches of annual precipitation to survive. If seeded thick enough and with moderate irrigation, blue grama will form turf. Once establish, reduce to monthly supplemental irrigation, and mow not more frequently than monthly to a height of 4 inches. One advantage of blue grama over buffalograss is the speed of germination; it will germinate in 5-7 days.
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.
Native woody shrub to Texas, New Mexico and west to California from 3000 to 8000 feet in elevation. It is best to plant in soil with only inorganic amendments. It becomes more floppy and flowers less when fed and watered well. This is a case of less yielding more.
Reseeds some. I've never seen this as a problem. Locate in a sunny area with full exposure to the sun for best growth and backlighting. If planted against a wall or fence it will lean towards the sun and looked tipped over.
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.
Snow on the Mountain is a showy plant native to the plains states. Heat and drought tolerant in the Texas Panhandle. Striking variegated green and white foliage, with small white summer flowers. Can be invasive and is toxic to humans, sap of plant may cause dermatitis. Deer resistant. Control spread by deadheading.
Sand lovegrass is a warm season bunch grass typically found in sandy soils east of the Rockies over a wide range of the U.S. The grass clumps themselves are usually 12-18" tall with the plumes rising to 3-4 feet. 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.
Bear grass is similar in appearance to yucca and clumping grass, but is neither. Usually found growing in high desert areas, along cliffs and rocky slopes. Thin succulent grasslike yellow-green leaves emerge from a trunkless center, are pointed and sharp edged. A plume-like inflorescence with many tiny cream colored flowers emerges early summer. Cold hardy, drought and heat tolerant.
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°.
Native perennial wildflower that will bloom periodically from spring into fall (presumably when there is adequate moisture). I have seen it many times in nature in the Texas Panhandle and West Texas. After the flowers have peaked, they do not fall off, but turn light and papery. They make a good dried flower. Reseeds!
This wildflower is toxic to sheep and possibly cattle. Humans should not eat any part of this plant. The flowers are fragrant and are attractive to bees, birds and butterflies.
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. Typically, desert globemallow sports pretty pink flowers. though some plants will bloom white, coral or lavender. Whatever color, they are worth the addition to your sunny and dry landscape for their pleasant cheery nature. Similar to appearane to S. coccinea, a coral blooming species.
Gregg's mist flower is a Southwest native for the partly shaded bed medium to low water-use bed. It's a butterfly magnet, particularly for the Monarch butterfly which passes through about the same time the mist flower is bloom in late summer into fall. Masses of lavender blue flowers top the plant for which it gets it names, the appearance of blue mist. Frequently, butterflies will be seen topping the flowers. Gregg's mist flowers will spread by roots, allow it some room.
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.
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. This native mockorange is similar in form to the European import, they are fragrant, but not of orange. Attractive white, 4 petaled flowers bloom in early summer, small slightly glossy green leaves. Coldy hardy, heat and drought tolerant.
Although usually sold as Clemantis paniculata, it could be C. terniflora. Sweetly fragrant, low water-use vigorous growing vine for great late summer display. Creamy white flowers form silvery seed heads. Cut back in spring as it blooms on new growth.
Wagons Ho! Rugged, ragged and windblown -- a true picture of the western and southwestern landscape. If you have a skeleton of a steer's head, now is the time to use it, along with that wagon wheel. Sometimes referred to as the western sage.
