Native Texas Panhandle soils amended with between 2-4 inches compost or other organic and/or amendments.
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.
The only draw back to this pretty, silver-edged groundcover is its flowers! If only it didn’t, it would be a perfect no maintenance, no water groundcover for hot, sunny locations. You can see the tiny ball shaped flower heads in the picture, which look rather indistinct. However, after flowering, they turn an ugly shade of brown that mar the beautiful leaves unless you shear them off. Though a creeping groundcover, silver-edged horehound is not invasive like the common horehound, M. vulgare.
Remarkable old Bourbon rose dating to 1868. Remarkable for fragrance and bright cerise pink flowers, and best of all, thornless canes -- it's people friendly! Not strictly a climber, but a mannerly climber.
Zephirin Drouhin is planted in a low water-use location.
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.
Strongly aromatic.
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.
Native to the plains, Coreopsis tinctoria, has naturalized throughout most of the U.S., especially in disturbed soil. Prefers moist sandy soil. An annual, it may last more than one year. Very showy flower with yellow outer rays, with a maroon blotch towards the center ray. Sow seeds in early spring. Heat tolerant, once a month watering is recommended for well drained soil.
It is so refreshing to see the rain lilies bloom after a long hot summer. Whenever they begin to bloom, I know the worst heat is over. Rain lilies are a delightful flower that sends up glossy green, grass-like leaves from its bulb in late spring. In mid to late summer, pure white flowers resembling a crocus open and continue through September, usually after a good summer rainfall. There are quite a few species and varieties (of various colors) of Zephrantes, however, Z. candida is the only rain lily cold hardy in Amarillo. I've grown it successfully since 2008.
Green santolina is an evergreen shrub native to the Mediterranean region. Its grass-green color makes it a welcome addition to any landscape. Medium and low water use, cold hardy, sun and heat tolerant, it prefers poorer soil. Aromatic green leaves that resemble those of the cypress. Yellow button flowers in summer.
