Soil that allows surface water to seep away into the subsoil not quickly or immediately, but within an hour's time and does not puddle.
Perennial from South Africa noted to be cold hardy for our area, but I’ve had mixed results, most years it didn’t winter over (although reported to be Zone 5). However, it will flower nicely the first year in the garden, so I’ve kept trying it. A Plant Select Plant for 2000. Perhaps it needs moister conditions in the winter than what I give it.
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.
Two southern native hibiscus suitable for the medium to high water-use garden. Large green leaves are superseeded by very large and showy flowers. H. moscheutos is cold hardy and has some of the largest flowers, up to a foot across in red, rose and white, usually with a red eye. H. coccineus blooms scarlet 3 inch flowers -- not cold hardy but worth trying as a specimen container plant.
Western sand cherry is a shrub native to the northern plains favoring sandy soils. Cold and heat tolerant, and low water-use once established. Beautiful, fragrant white flowers in spring time, producing edible black cherries (however, some references advice not to eat the fruit if it is bitter).
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.
Sedum, ‘Autumn Joy’ is one of those foolproof additions to your autumn garden, so aptly named; for the joy it brings to the autumn garden. Easily propagated by stem cuttings or root division. As with most sedums, afternoon shade helps. Grasshoppers have nibbled at its leaves in early summer without stunting the plant’s flowering ability.
Lantana urticoides (horrida) is a native perennial, and cold hardy for most of the state, except for areas in the Texas Panhandle. In the Panhandle, several species of Lantana are sold as summer bedding plants. Blooms prolifically summer and fall. Colors normally available are red, red and yellow, yellow, white and purple or mauve. In rare cases they may winter over. In areas south, lantana will grow into a shrub. The blue/black fruit clusters are poisonous.
Gambrel oak is a common native oak species throughout the Rocky Mountain foothills and here in the Texas Panhandle as well. Often times it grows more to a tall shrub, with sufficient moisture it can mature into a small tree. Beautiful somewhat glossy lobed green leaves to 3-5 inches long. Beautiful fall foliage. Will put out a profuse amount of acorns. Gambrel oak can form a thicket. Cold, heat and drought tolerant. Inconspicous tiny red flowers appear shortly after leafing and are normally hid by the leaves.
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.
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.
Maypop, or passion vine, is a perennial vine native to eastern and southern areas of the U.S. In the South, maypop grows into a woody vine, but in northern areas like the Texas Panhandle, it will die back to the ground. Lobed, dark green leaves, beautiful, unique flowers emerge in the summer to fall, producing edible fruit. Maypop will sucker, especially when ample watering is present. Passion vine, the most cold hardy of the genus, should be cold hardy to Zone 6.
Shrub live oak, often a medium size shrub, is native to the Southwest and the Texas Panhandle typically found in canyons, rocky cliffs and hillsides. Sometimes called a holly oak, the leaves are 3-4 inches long, spine-tipped and holly shaped bluish green leaves. It is prolific in putting out acorns. Cold hardy, heat and drought tolerant.
A tuber mostly grown in containers or a summer groundcover, not considered cold-hardy in the Panhandle. Striking purple-black foliage with small light magenta flowers, similar in appearance to bindweed. Ipomoea’s are members of the bindweed family, Convolvulaceae. One bad relation doesn’t have to trash the family, however.
I prefer dwarf chamisa to the full size species. Dwarf Chamisa fits better into home xeric areas and has green leaves, rather than gray or silvery. It's silvery stems combine well with its green foliage and yellow gold flowers. Although given the species and variety name "nauseosus" it has a pleasant fragrance. Dwarf chamisa blooms profusely in late summer and will readily re-seed.
Fame flower, flame flower, or rock pink, is a Midwestern native succulent. Ideally suited to western rock gardens, short fleshy narrow leaves emerge in late spring, followed by wiry stems where tiny rose/pink flowers open up each afternoon. In fall, the top foliage dies off and the plant heads underground for the winter. Because of it's unusual nature, it can be tucked in anywhere at the front of a border, just don't forget where you've planted it when doing spring cleanup. Reseeds slightly.
Phemeranthus calycinum was formerly known as Talinum calycinum.
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.
This pink (old common name referring to the pinked edges) is pink. Heat tolerant fragrant perennial forms a spreading mound. The buds provide interest for several weeks before they open. Other perennial dianthus thrive in our area, biennial and annual dianthus as well. Look for heat tolerant varieties. D. gratianopolitanus ‘Firewitch’ is another dianthus to try. Carnations, maiden pinks, Sweet Williams are members of this genus. There are many hybrid cultivars, and more every year.
Victoria blue salvia is usually not cold hardy in the Texas Panhandle, but every once in awhile, one will winter over. But that shouldn't stop you from replanting this lovely, summer long blooming native to regions further south, classified by some to be one of the top ten flowers for Texas gardens. Upright and dense flower stalks in blue, white (Alba) and deep blue or violet. Salvia farinacea continues to be hybridized to create new introductions. Often referred to as mealycup sage, its stately appearance deserves the nobler moniker, Victoria Blue.
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.
The vitex, or chaste tree is a small tree or a very large shrub, depending on water and climate, and is cold hardy to the Texas Panhandle. Low water-use once established, it can grow well in higher water zones. It is called the summer lilac because of the similarities of its flowers to the lilac shrub. Vitex varieties can be found in blue, lavender, and pink fragrant flowers. The leaves are similar to those of the marijuana plant. Vitex will sucker, especially when given ample water. It is native to southern Europe and Western Asia.
‘Red Rocks’ is another hybrid cultivar, named for the Denver, Colorado red sandstone area and amphitheater. P. 'Red Rocks' is highly suitable for the average garden, rather than a specialized penstemon bed. Again, do not deadhead unless reblooming has occurred and you desire a tidier appearance. Don’t over water or over amend the soil, but it will thrive companionably with other medium water-use plants.
Most notable in the meadows and fields of California, the California poppy grows throughout the southwest. Considered to be both annual and perennial, it either comes back the next year or it reseeds. Once you have a stand established, it should continue in your landscape, but not invasively so. This past summer of 2012, my California poppies bloomed in both the spring and our unusual fall. Blooms in April and May. Finely cut blue-green foliage make an attract plant outside the bloom period. The foliage should die back in summer.
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.
Gayfeather is one of the High Plains jewels of autumn, sending up grasslike leaves or stalks that bloom gloriously in September and October to fuzzy purple spikes. At maturity, one plant can grow a dozen or more, size and number depending on rainfall amounts. Drier years, the stalks are few and short, but with monthly or twice a month watering, the plant displays much more vitality. The purple flowers contrast nicely with the many yellow flowers that bloom on the plains. Liatris punctata is the most drought tolerant of the genus.
A long-lived evergreen penstemon for the average bed or border. Small orange red tubular flowers attract hummingbirds, as do most red tubular flowers. Low growing and longer flowering than most, especially the more mature the specimen.
After several years, the pine needle like foliage can resemble a miniature bonsai. Pineleaf penstemon is also a must-have for the low water-use bed or border or rock garden because of its evergreen foliage and longer blooming nature. In late summer, snip off the dried, spent flower heads; some re-blooming may occur.
