A perennial plant is a plant that requires one or more years to reproduce and usually continues living, but not indefinitely. Whether a plant is cold hardy or not is not connected to being an annual, perennial or biennial.
Native to a large part of North America, golden rod is a pleasant addition to your native garden, and contrary to popular myth, does not cause allergies; the pollen is too heavy to be wind born. But choose a variety of Solidago that does not have invasive rhizamatous roots for lower maintenance.
Attracts bees and butterflies.
Lady in Black aster is an improved selection over the Midwestern native, Aster lateriflorus (now Symphyotrichum lateriflorus). Dark canes with musty purple leaves provide a striking contrast in the flower beds and borders that become covered with tiny white aster flowers with pink centers. Truly stunning bee and butterfly magnet for about 3 weeks in autumn.
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'. During early autumn snows, be quick to shake snow off the branches to avoid breakage.
Solidago rugosa 'Fireworks', arching branches similar to S. canadensis 'Golden Baby', only is low water-use and more golden in color. Fireworks goldenrod will also flower in summer and again in the fall. Makes a great splash in the summer garden.
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.
Utah serviceberry is a quite beautiful shrub extending from the Southwestern states northward throughout the Rocky Mountains and through various ecosystems between 4000 and 8000 ft in elevation. Deep green leaves, large oval shaped and toothed at the margins, many intricately branched, smooth gray to maroon bark. Large white flowers with five widely spaced petals open in May and June. Berries appear in the summer, ripening to pink, then red, then finally dark blue. Leaves turn red and orange in the fall.
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.
Beautiful xeric sage with aromatic soft gray green leaves, mostly evergreen. Summer to fall blooming with mauve/purple sticky but fragrant flowers. Takes a few years to reach mature height. Requires good drainage and dry soil in the winter. A Plant Select® Plant. Native to California and will grow in the High Desert regions. Cold hardy to Zone 5 and quite heat tolerant.
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.
This is an improved variety to our native gaura, it is known to be short lived for 4 – 5 years, but is worth replacing periodically for its spectacular fireworks display. Placed as a focal point, G. lindheimeri ‘Whirling Butterflies” was the plant most commented on in my front garden. Native more to eastern Texas and Louisiana, a terrific plant for city or country in a medium water-use location. Any plant with long wispy stems that flows with the wind is an asset to your border. Other cultivars to use are ‘Siskiyou Pink’ and ‘Pink Cloud’, two pink varieties.
Nandina is one of a few single species genera, a member of the barberry family (Berberidaceae). Though one species, several cultivars are available to add texture and interest to our low maintenance, low water-use landscape in either sun or shade. I plant mine in full shade, as there are few shrubs that will flower there. I personally favor protecting Nandina with afternoon shade, if planted in a sunny location.
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.
This variety purchased from Sunshine Nursery in Clinton, Oklahoma is drought tolerant, I've planted it in a low water-use bed. The flowers are so dense and golden, it looks like a golden torch. Sometimes seen as Solidago speciosa rigidiuscula, 'Wichita Mountains'
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.
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.
Low water-use non-native hybrid shrub (Artemisia arborescens x Artemisia absinthium) from Europe and Asia. Vigorous grower, do not overwater. Coldy hardy to Zone 6. Ever-silver with elegant finely cut leaves. 'Powis Castle' is named for Powis Castle in Wales. Rarely flowers.

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.
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.
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.
Hyacinths are a much loved and very fragrant spring bulb, flowering in March and early April in our area. Clusters of bell-like flowers dangle from a central stem. Native to Asia, hyacinths were one of the early favored flowers by the Persians, Turks and Europeans, in fact, practically everyone who came in contact with them. Easy to grow in full sun to part shade in average garden soil. Hyacinths come in many pastel colors, both single and double flowers.
