Plants are known to be cold hardy to at least -10°F.
A native to Texas, flame acanthus loves the heat and full sun! A hummingbird and butterfly plant. Does well in poor soil. May only be cold hardy to Zone 7, however, it has come back for several years in the Panhandle. Grows rapidly and will flower the first year, if you must replant, this is still a good choice for mid to late summer and autumn flowers. Re-seeds some, transplant them early as their roots grow deep.There is another variety with light pumpkin colored flowers, but this one does not bloom as prolificly.
A terrific variety for the prairie garden, though requiring prairie conditions -- good soil with good drainage and more frequent watering than our native, E. angustifolia. Coneflowers are all the rage right now with many new introductions every year, ranging from white, yellow, orange to the popular purple. Most of these should be located in your medium to high water-use area. The richer the soil and with weekly watering (high), you'll enjoy grander blooms. A good border plant in the transition area between turf and medium water-use. E.
Grown in the South for decades, most people think of crape myrtle as a native American plant; it is however native to China and Japan. Small tree or large shrub that is cold hardy to Zone 7. I’ve grown the same crape myrtles for over 20 years, but they’re planted close (too close!) to my bricked house on both the northeast and northwest corners. They’ve been stem hardy, not just root hardy, and have grown up to about 10-12’. In most cases, crape myrtle will not grow into tree form in the Panhandle, but there are mature, tree size crape myrtles in Amarillo.
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.
A new hybrid skullcap from High Country Gardens. A cross between two native skullcaps, Violet Cloud likes the soil lean and well drained. A sparkling addition for the rock garden, xeristrip and any low water-use area. Additional watering is required during establishment the first year, after that, it should be drought tolerant.
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.
Golden current makes an attractive taller shrub at the edge of a lawn or vegetable garden, positioned to catch extra irrigation water. For three stunning weeks in spring it will be covered with tiny yellow flowers. I planted two in 2008, and have yet to notice the tasty berries, red currents, for which they are known. Quite cold hardy, if placed in full sun, it'll need twice a month watering to survive, or in half or more shade, once a month watering is sufficient. Multi stem shrub with small, rounded leaves with cut edges makes an attractive barrier or hedge plant.
Similar in form to Callirhoe involucrata, Callirhoe alcaeoides 'Logan Calhoun' grows natively from the Midwest to southern plains. While Callirhoe alcaeoides can be pink, to pale pink and pale lilac, 'Logan Calhoun' is pure white. Spreads over an area similar to wine cups, the foliage and flowers are finer. I've found it to be drought tolerant; water monthly to insure continued blooms. Blooms will rest during the heat of the summer and continue following rains or cooler weather.
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.
Three leaf sumac is medium height woody shrub native to the Texas Panhandle and throughout the Southwest. Three distinctive cleft and lobed leaves (trifoliate) are medium to dark green. Small greenish yellow flowers in spring are followed by tart red berries in summer, which are used to make a lemonade-like drink. The shrub's flowers have a pleasant fragrance, even though it is called skunkbush by some. Beautiful golden and reddish fall foliage. Cold hardy to Zone 4, yet extremely heat and drought tolerant. Prefers sandy and well drained soils.
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.
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.
A beautiful white variety of the purple coneflower. This picture doesn't do the flower justice.
Similar to the purple coneflower, this white variety is really a high water-use plant that appreciates afternoon shade. Deadhead to prolong the bloom period, but keep end of season blooms on for fall and winter interest.
Outstanding shrubby perennial fragrant herb for the garden! Very good soil drainage is the key to growing lavender, it does not like moist, compacted clay soil. Lavender appreciates supplemental irrigation every 2-4 weeks, if not provided naturally. Trim back in late winter or early spring by not more than a third, or just trim down last years flower stems. Triming too much off the plant will kill it.
The most remarkable quality of Red Dragon Persicaria is its burgundy red patterned leaves and red stems, a plant grown much more for its foliage than flowers. (The flower stalk in the upper right is of Acanthus spinosus.) Not a native (native to China) it will come back if nipped by a late frost and will suffer sunburn in afternoon sun. Red Dragon may take 3 years before flowering, however, that is not a drawback.
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.
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.
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. If your stand becomes too dense or too much, just weed some out. They're adaptable to most native soils and will thrive on available or once a month supplementation. Coneflowers bloom yellow, reddish or brown late spring into fall and make an attractive display when mixed.
People either love trumpet creeper or hate it. The first three years, I couldn't wait for it to mature, filling with red-orange trumpet shaped flowers. It seems I've spent the next 20 years trying to kill it. Trumpet vine will die, but only for those who want it to live. If a gardener gives it the death wish, it will be sure to flourish. Native to most of the eastern half of the U.S., it is low water-use, thrives in heat. Must be in a sunny location to bloom profusely. Considered to be invasive, especially when over watered. Not particular about its soil.
Raspberry hybrid bush sage is very similar in appearance to Salvia greggii, blooming April through November. It's two-lipped flowers with a pleasant deep raspberry color, and the mahogany calyces contrast nicely. 'Raspberry Delight' is a hybrid cross between Salvia greggii 'Furman's Red' and and a high altitude collection of Salvia microphylla from central Arizona. Woody and brittle branches with small oval shaped leaves that hang on to the plant sometimes through the winter, as they do on S. greggii.
Ephedra minimus is a dwarf version of E. viridis. Woody base with many thin, branched evergreen stems. Rare to find in nurseries, it is appreciated for is evergreen presence and rarity. No leaves or flowers
Snowberry is a woody plant that spreads from the roots, sending up arching branches every couple of inches to about 3-4 feet high. The small green leaves are pleasant as are the white spring flowers, followed by the remarkable pearly white berries. During the summer, I inspect the snowberry bush weekly for signs of the berries. They never remain long on the bush, as the birds quickly devour them (they're said to be toxic to humans). Snowberries thrive in part shade and medium to low/medium watering. they easily propagate by digging out and transplanting the roots.
Native herbaceous perennial to the central and eastern U.S.; will grow in a variety of soils, including poor soils. False blue indigo did not flower the first year. Flowering improves as the plant matures. The foliage may go dormant and disappear towards the end of summer. Baptisias belong to the pea family (Fabaceae), a legume. Flowers are similar to a lupine. Other species colors are white (B. alba) yellow (B. sphaerocarpa), and other variations and cultivars, including 'Chocolate Chip', which features a light reddish brown flower, similar to milk chocolate.
First class native wildflower for your low water-use location whether you live in the city or country. No soil amending is even needed for Engelman's daisy, but you might want to improve the drainage if you soil is compact, or amend with some organic matter for caliche soil. Toowell amended soil will cause E. pinnatifida to grow too tall and gangly. If this happens, cut down nearly to the ground at the end of June, or mid July. It will grow back and begin flowering within 3 - 4 weeks. Will reseed some.
