Native Texas Panhandle soils amended with between 2-4 inches compost or other organic and/or amendments.
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 native to Texas, flame acanthus loves the heat and full sun! A hummingbird and butterfly plant. Does well in poor soil. May only be cold hardy to Zone 7, however, it has come back for several years in the Panhandle. Grows rapidly and will flower the first year, if you must replant, this is still a good choice for mid to late summer and autumn flowers. Re-seeds some, transplant them early as their roots grow deep.There is another variety with light pumpkin colored flowers, but this one does not bloom as prolificly.
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.
Reseeding biennial, native to Texas, and the southeastern US. The red tubular flowers make it attractive to hummingbirds. The upright stalks are brittle and break off easily.
Standing cypress will flower the first year, and may, or may not come back a second year, but you should see some seedlings. Transplant those. The glossy green foliage to the right in this picture belongs to Anisacanthus quadrifidus wrightii, flame acanthus.
‘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.
A Plant Select Plant for 2004, Pink Texas Skullcap has often been listed as a Zone 7 plant, but it is reliably cold hardy in Zone 6 and in protected Zone 5b sights. I’ve grown it in my xeristrip since 2000. Long blooming with no maintenance ever performed. These low growing, mounding skullcaps are excellent for Panhandle xeristrips and rock gardens. Native varieties are S. drummondii, and S. resinosa. The hybrid cultivar, S. x ‘Violet Cloud’, introduced by High Country Gardens, is an excellent violet skullcap as well as the natives.
Verbascums make a presence in the wildflower or cottage garden and mixed border, whether it be this common mullein, or another species with showier flowers. Verbascums can be either biennial or perennial, but will make enough seeds you’ll never be without. Some are drought tolerant and thrive in poor, but well drained soil, others may need medium water use and a richer soil.
Agastaches are some of the Southwest's showiest natives and one of our native perennials where must breeding and hybridization is being done. Native to slightly higher elevations that 3600 ft., it requires either afternoon shade or medium water-use. It has not been reliable in coming back for me, but it has for others. Well drained soil is a must. Nonetheless, it is easy to be seduced by its masses of blooms and alluring fragrances. Hummingbirds certainly are entranced.
Virginia creeper, one of our pernicious native creepers, is a worthy low care vine for brilliant fall foliage and deep blue berries (highly toxic to humans) loved by birds. Virginia creeper normally spread by seeds in bird droppings, which is the method it came to my landscape. When spotted early, Virginia creeper easily pulls out, but if not spotted, within no time, it will cover a fence, climb a pole or cover an area. Which can be either a good thing or a bad thing, depending on one's view.
Curl leaf mountain mahogany is a medium height evergreen shrub native to elevations between 5000-10,000 feet throughout the Southwest. Small oval shaped dark green leaves lightly curl under at the margins are evergreen and aromatic. Small yellow flowers in spring time that develop into grain size fruits with a feathery tail attached to one end (similar to other mountain mahoganies). Slow growing and long lived, it can reach a height of 20 feet or more, but is more typically 6-12 feet. Densely branched. Cold hardy, drought and heat tolerant.
Showy evening primrose is a plains states native, including the Texas Panhandle. Showy evening primrose blooms whitish pink in late spring, with each flower lasting a single day, opening in the morning and closing later in the day. The leaves are green narrow and lance-like and emerge from spreading rhizomes. The plant spreads prolifically by rhizomes and seeds, especially in amended and well watered soil. It is not well mannered in a mixed bed or border, I consider it invasive for the garden.
Native herbaceous perennial to the central and eastern U.S.; will grow in a variety of soils, including poor soils. False blue indigo did not flower the first year. Flowering improves as the plant matures. The foliage may go dormant and disappear towards the end of summer. Baptisias belong to the pea family (Fabaceae), a legume. Flowers are similar to a lupine. Other species colors are white (B. alba) yellow (B. sphaerocarpa), and other variations and cultivars, including 'Chocolate Chip', which features a light reddish brown flower, similar to milk chocolate.
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.
Perennial with lyre shaped leaves, similar in appearance to scabiosa, native to central Europe. In fact, it's synonym is Scabiosa rumelica. Deep purple red pincushion-like flowers. Knautia macedonica may suffer from our alkaline soil if not well amended with compost and well drained. Will reseed some. Has a pleasant wild look. Popular with nectar feeding insects. Deadheading doesn’t seem to be necessary.
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.
Our native skullcap is one that should be included in every drought tolerant landscape, short lived though it is. This is the kind of garden-worthy plant we all desire, neat, compact and all season blooming with no maintenance to speak of. You just can't go wrong as long as your soil has decent drainage. It reseeds some, but to me, this is just a bonus.
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.
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.
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.
Ephedra minimus is a dwarf version of E. viridis. Woody base with many thin, branched evergreen stems. Rare to find in nurseries, it is appreciated for is evergreen presence and rarity. No leaves or flowers
Prairie verbena is one of my favorite plants, it is one of the first to bloom in the spring and one of the last to be affected by freezes in the fall. Small in stature, but it has my respect for giving so much with so little given (from me) in return. It's short lived, maybe just one year or three. Green, finely cut hairy leaves, with several branched stems that put on clusters of tiny lavender, purple, violet or pink flowers. Blooms from spring to fall. Readily reseeds, not invasively so. Its volunteer seedlings are easy to dig up and transplant.
Terrific taller plant for the late summer garden. Native from eastern U.S. that grows well here too in a medium water-use area. Talls stems with numerous yellow centered, small aster-like white flowers that look similar in appearance to Michaelmas daisies. Propagation by root division in spring or by seeds. Does reseed some. Other varieties are 'Snowbank' only to about 4-5' but with larger flowers, and 'Pink Beauty' with pink flowers.
Echinacea angustifolia is the herbal echinacea. Native throughout most of the Midwest, and the Texas Panhandle. Very drought tolerant. It can be seen growing along roadsides and in nature generally. A good cut flower. The common name Black Samson refers to its roots. Not as showy as E. purpurea and newer introductions.
Distinctive flat, thin upright leaves with flowers arising from the stem.
‘Mersea Yellow’ is similar to the orange red pineleaf penstemon in culture, except for requiring a bit more water. Native perennial to the Southwest. Its leaves are lighter green, but still evergreen, without the tinge of mahogany in winter. ‘Mersea Yellow’ is an excellent selection for the medium water-use zones of your landscape. One of the few yellow flowering penstemons.
