Native Texas Panhandle soils amended with between 2-4 inches compost or other organic and/or amendments.
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.
Rose of Sharon, or Althea, is another reliable old-fashioned garden plant well suited for the Texas Panhandle. My favorite cultivar is Diana because of the brilliant, pure white 4-5” flowers and somewhat glossy green leaves. Diana is also one of the smaller varieties up to about 6 - 8 feet, while others can reach 10’ tall. Similar to most altheas, 'Diana' is a prolific bloomer.
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.
1997 Perennial Plant of the Year was chosen for it versatility in growing in many different regions of the US. And it will grow in our Panhandle gardens as well. Although reported to be drought tolerant once established, it does much better in a medium water-use environment with afternoon shade. When it is excessively hot and dry, it suffers from stress, but usually survive. Just give it a little more water when this happens.
Attractive to bees and butterflies. Seedlings may happily appear in springtime. Native to Europe and Central Asia.
Rudbeckia is advertised as heat and drought tolerant, but I have not found it so. I’ve found it to require at least weekly watering during the heat of the summer. A shortlived, southern native perennial, it likes the humidity and rain from southern climes. These very large and stunning composites may be worth your effort, just place within the correct hydrozone.
Warm season native clumping ornamental grass that is well suited to the transition zone between turf and flower bed. Medium to blueish green thin grass blades form a low to medium size clump, medium water-use zone. In late September, it sends plumes upward that give the appearance of a deep pink haze or mist. There are several new selections of Gulf Coast muhly, thankfully, to choose from. Be sure to pay attention to the cold hardiness for your area and you won't be disappointed.
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.
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.
Delicate and fragile in appearance, columbines are some of the most durable, versatile plants in the West. Aquilegia chrysantha is the Texas native columbine, happy in both sun or shade, moist areas or dry. Aquilegia chrysantha is native to the Chihuahuan and Sonoran Desert canyons from west Texas, southern New Mexico, southern Utah, and Arizona south into Sonora, Coahuila, and Nuevo Leon along with a disconnected population in southern Colorado.
