Leaf color is one of the hues of green, other the gray-green or blue-green.
Karl Foerster feather reed grass is a cool season bunch grass one of the best ornamental grasses for a medium or high water-use area. In a low water-use area, it will take longer to reach mature height and width (the more water it gets, the bigger it'll get). Karl Foerster feather reed grass suffers in the xeric bed during the hotter, drier drought years and may die out.
It's hard to pass up Johnson's blue geranium with the deep blue flower and interesting foliage. A hybrid cultivar, the most blue hardy geranium with delicate, finely cut leaves. Plant in your woodland border, medium water use. For a long time this was the most well know hardy geranium, or cranesbill, as this genus is commonly known.
When the name geranium is spoken most of the time, people are referring to the genus, Pelargonium, the red flowering perennial that is used extensively throughout the world. the common Pelargonium is only cold hardy to 28°.
Gorgeous! Luscious goblet shaped lemon yellow flowers on this native wildflower that also develops elongated seed capsules. The lighter, silvery sheen of the leaves distinguishes the O. macrocarpa var. incana subspecies, and is also an evening to morning bloomer.
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'
Calamint, a member of the mint family, sparkles with white/pale lavender flowers in late summer into fall. Solid green foliage emits a pleasing mint fragrance. Attracts bees. Sometimes referred to as lesser calamint. Calamintha nepeta spp nepeta covers itself with light blue flowers.
Not all succulents are cacti, nearly all cacti are succulents (a few exceptions). Nearly all cactus species are native to the Americas, providing a prickly evergreen presence. There are many cactus that are cold hardy for the Texas Panhandle. There might be one for your garden.
Tansy aster is an annual native to the Southwest and throughout the Plains even into Canada. Fernlike, or tansy-like (tannacetifolia) light green foliage with beautiful aster-like lavender flowers with yellow disks about 1 1/2 to 2 inches across. Blooms from late spring through fall. A once a month watering will keep the blooms coming throughout the summer. It will keep its compact shape in lean, poor soil but will become much larger in well amended soil. Minimal amending is recommended. Tansy aster is another example of our natives plants giving so much, asking so little in return.
Turpentine shrub is an evergreen shrub native to the southern parts of the Southwest, and only marginally cold hardy on the Caprock. It will survive when in a sheltered location and soil with excellent drainage, along rocky cliffs, outcrops and arroyos. Avoid compact clay soil, or amend clay soil very well for drainage with inorganic amendments. Yellow autumn flowers.
Bush morning glory is a non-vining herbaceous perennial with a deep taproot, allowing it to be drought tolerant, but difficult to transplant. Arching branches with narrow upright green leaves emerge from the taproot. Summer blooming with 3 inch pink to purple funnel shaped flowers that open in the morning and close in the afternoon. Bush morning glory typically inhabits sandy and sandy loan plains, meadows, prairies and roadsides.
Butterfly bush is a perennial shrub that comes in many colors from white, yellow, pink, rose, to mauve and deep purple. Native to China and is available in many different hybrids, cultivars or varieties. Quite fragrant, attracts butterflies. Butterfly bush needs very good drainage, it will not tolerant wet clay soil. It will grow in poor soil with good drainage. Butterfly bush trives quite well in low water-use areas. Alternate spelling is Buddleja. Not invasive in the Texas Panhandle.Several species are native to parts of Texas and Mexico. B.
Cranesbill belongs to the same Geraniaceae family as do the Pelargoniums, those red, hot house geraniums we all love. Both are perennials, however many cranesbill (referred to as the true geraniums) are cold hardy for us. Alpenglow is semi-evergreen, and evergreen in warm winters. Notice the intricate cut leaf patterns, which are much admired by myself and others. A good understory plant for the edge of a shady border.
Exciting perennial ornamental oregano for your low water-use or Mediterranean style garden. Spreads slowly by rhizomes and is easily propagated by root cuttings in fall or early spring. The flowers elongate as the summer progresses, eventually drying to a papery brown by summers end. In a wet fall, some new flowers may still appear. O. libanoticum is best placed to drape over a rock to showcase it’s drooping nature.
There are numerous interesting yuccas to choose from besides the Yucca glauca or Y. angustifolia seen throughout our area. Y. filamentosa ‘Color Guard’ has some of the most striking variegation and will even flower in part shade, cold hardy to Zone 5. Other Y. filamentosa varieties to consider growing in our area are ‘Bright Edge’ and ‘Golden Sword’.
The Calylophus genus is one of the best Southwest native plants for Panhandle gardens. Heat and drought tolerant, long blooming with little to no care, what garden would be without it? Sunny yellow 4 petaled sundrop flowers bloom in an explosion in spring, and respectably during the remaining growing season, especially when given a once a month inch of water during drought conditions. Each individual flower lasts only a day, tight compact mounds sport the orange spent blooms as well as the new bright yellow flower.
An American native requiring medium to high water, it is a prolific grower, an old fashion pass-along plant. Perfect for a mixed border or at the edge of the vegetable garden to attract bees. The variety shown is most likely 'Violet Queen', although I'm unsure. However, it is not the common scarlet bee balm or red bergamot, that also grows well here. Blooms throught the summer and is an attractive addition.
Bigelow's tansyaster is easy to confuse with Tahoka daisy but is not as showy. Bigelow's aster is a fall blooming biennial, with far fewer purple rays and a smaller, yellow brown center disk. It populates plains in Colorado, Arizona and New Mexico. In the fall, whole fields will wear a purple haze due to this tansyaster.
Cliff fendlerbush is another Texas and Southwest native shrub too little used in the xeric landscape. Springtime lifts the cliff fendlerbush above the ordinary into prominence in the landscape. It is said the ravines and arroyos look dotted with snow from a distance, so profuse are the fragrant, creamy white, sometimes with a pink tinge, four petaled flowers in May and June. It's natural element is rocky arroyos (rupicola=rock dweller), cliff ledges and limestone soils with good drainage that average 12-18 inches of moisture with hot sunny days.
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.
Caladium corms are tropical plants grown for their summer foliage, however they do send up an arum type flower (a member of the Araceae family). Foliage comes in many different variegation patterns in red, pink and white. There are a over a thousand cultivars, most from the Caladium bicolor species. Plant bulbs after May 1st, only about 3 inch deep. Caladiums like it hot and moist. Complete shade works OK, or morning sun only.There are a few sun tolerant cultivars available. For larger leaves.
Green sword-like foliage with striking bell or funnel shaped flowers that last only a day. Hundreds of different hybrids and cultivars in a wide range of colors, some early, mid and late summer blooming. Daylilies do better in medium, well-amended soil and a sunny location that enjoys afternoon shade, but they are versatile. Daylily leaves may exhibit alkalinity in clay soil. If this is the case, amend well with organic matter.
‘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.
Grown extensively throughout the southwest, I don’t know why it has taken so long for this plant to become available in the Panhandle, especially since it is cold hardy to Zone 5.
It is a bit slow to become established, and late in coming out in the springtime – have patience and place a marker so it’s not forgotten and weeded up. Note: Early spring-emerging plant may look similar to bindweed. It is best to plant this wild fuchsia in spring, rather than the fall. I noticed better success with quart to gallon size plants.
Previously known as Cowenia mexicana, it is known today as Purshia stansburyana, also, P. stansburyiana. It is still commonly called a cliffrose. The cliffrose blooms prolifically in May with creamy white to pale yellow fragrant flowers that continue blooming for several weeks. Semi evergreen, it loses it's leaves in colder winters. Upright stems and branches can appear unruly in its growth pattern; small dark green resinous leaves.
One of North America's favorite annuals. There is much variety in size and colors of flowers, ranging from yellow, golden, orange, red/orange, red and mahogany. The plants themselves can vary from 3-4 feet to 8 feet or more. Seeds sown in springtime will be insure blooms in late summer or fall. Great for cut flowers.
Rounded mounds of green leaves on multi-forked stems put forth multitudes of fragrant purple/magenta flowers from summer into autumn. Flowers open in late afternoon (perhaps around four o'clock) and close in early morning. Cold hardy and heat and drought tolerant, after freezing in the fall, the top growth breaks away. Desert four o'clock emerges in the spring from a large root. Will not transplant well once established. Southwest native perennial is usually found in somewhat shaded areas.
