A plant will shed its leaves, usually during the autumn months and through winter.

Common Name: Jupiter's Beard, Red Valerian

Centranthus ruber is a versatile plant, able to be used almost anywhere in the landscape except full shade. Long blooming except during the heat of the summer. Deadhead after the spring bloom for better appearances. Reseeds some, but not a problem. Quite drought tolerant, it will still do nicely in medium and high water use areas, except for wet, soggy clay. It appreciates good drainage and moderate amending but will do well in poor soil. Centranthus ruber 'Alba' is a pleasant white blooming variety. Readily available at local nurseries.

Common Name: Pineleaf Penstemon

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.

Common Name: Furman's Red Autumn Sage, Cherry Sage

If I had to pick my favorite plant, this is it. Long blooming and drought tolerant with only minimal maintenance of late winter cutting back, and maybe a bloom pick-me-up deadheading at mid summer. It will also re seed some so you’ll have more of them the next year. It’s fragrance is light and pleasantly of sage. Salvia greggiis are native to Texas in the Kerrville area. It is my favorite, but not the absolutely perfect plant. The stems are quite brittle and very easily break or snap off, even when you’re carefully weeding around it.

Common Name: Gro-Low Sumac

Sumacs are known for brillian fall foliage. Ground cover woody shrub 24-30" tall with dark shiny green leaves that turn a thrilling orange-red in the fall. Small yellow flowers at springtime.

Common Name: Illinois Bundleflower

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.

Common Name: Switchgrass

Switchgrass is one of the best native ornamental grasses of our tall prairies. Switchgrass forms upright bunches of wide 1/2 inch green blades, with open pale purple inflorescence arising another 2 feet in late summer to fall. Switchgrass will thrive with every other week supplemental irrigation. There are many varieties of switchgrass, 'Prairie Sky' is the most drought tolerant (low, xeric) with blue blades. Other fine selections are 'Heavy Metal' with metallic lavender blue foliage turning reddish towards fall, and 'Shenandoah' with leaf blades tipped in red.

Common Name: Larkspur

The old fashioned larkspur is a drought tolerant reseeding annual, previously associated with delphiniums (now in the Ranunculaceae family). I’ve grown it in my alley, in the xeristrip, and its crept into my medium water-use zone. Deadheading keeps millions of tiny seeds from overcoming your garden next year, and also keeps the blooms coming. Larkspur can flower for six weeks. Again, deadheading is important to prevent a massive infestation throughout your landscape.

Common Name: Mersea Yellow Pineleaf Penstemon

‘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.

Common Name: Rock Rose, Rose Mallow Pavonia

Although there is question in my mind whether pavonia is a native in Texas, it’s been naturalized for a long time and is found growing in the Edwards Plateau and south Texas. Pavonia has been cold hardy for me for at least 5 – 6 years. Readily reseeds to the point of being a nuisance, but this is a minor annoyance.

Common Name: Blue Mist Spirea

Rarely does a shrub feature as much versatility as the blue mist spirea. It will grow and flower in sun or shade, low water-use or high. This Caryopteris, a hybrid itself, normally blooms in a pleasant light blue, but other selections have deeper blues hues. Summer blooming into fall. And as unlikely at it seems for hybrid to set viable seed, blue mist spirea reproduces itself pleasantly, never invasively. Indeed, any little volunteers are welcome.

Common Name: Snow on the Mountain

Snow on the Mountain is a showy plant native to the plains states. Heat and drought tolerant in the Texas Panhandle. Striking variegated green and white foliage, with small white summer flowers. Can be invasive and is toxic to humans, sap of plant may cause dermatitis. Deer resistant. Control spread by deadheading.

Common Name: Alkali sacaton

Alkali sacaton is a perennial warm season bunch grass native to the Southwest. In late summer to fall, airy triangular seed heads wave above the silver green grass blades. Grows in alkali soils, many say in locations where there is moisture nearby, prefering heavy clay soils. It is quite drought tolerant once established, and long lived. It will, of course, grow bigger or smaller depending on water resources.

Common Name: Yellow Corydalis

Delicate fern like foliage for your shaded woodland areas. Will grow in a low water-use zone, however, the foliage will disappear in summer. Delicate tubular, yellow. White and blue varieties have been available locally. An excellent choice for underplanting trees, especially for a medium water-use zone.  Will reseed.

Common Name: Russian Sage

Russian sage is a must have shrub for every low water-use landscape. Russian sage is used extensively throughout our southwest landscapes, planted along with Buddleia, Carl Forester Reed Grass, Salvia greggii cultivars, Anisacanthus quadrifidis wrightii and Hesperaloe parviflora. It is hard to beat its use where a long flowering, showy, low care, drought tolerant shrub is needed.

Common Name: Texas Pink Skullcap, Cherry Skullcap

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.

Common Name: Golden Current

Golden current makes an attractive taller shrub at the edge of a lawn or vegetable garden, positioned to catch extra irrigation water. For three stunning weeks in spring it will be covered with tiny yellow flowers. I planted two in 2008, and have yet to notice the tasty berries, red currents, for which they are known. Quite cold hardy, if placed in full sun, it'll need twice a month watering to survive, or in half or more shade, once a month watering is sufficient. Multi stem shrub with small, rounded leaves with cut edges makes an attractive barrier or hedge plant.

Common Name: Broom Snakeweed, Broomweed

Broom snakeweed is a small mounded subshrub with yellow greenish thread-like leaves, native throughout the Southwest and western half of the North American continent. In the fall, it becomes covered in small golden yellow flowers. Bees and nectar butterflies are attracted to it in numbers. Usually grows to only a foot tall.

Common Name: Giant Sacaton

Giant sacaton is one of the largest bunch grasses native to the Southwest, like alkali sacaton on steroids. Seems to thrive in poor soils with no supplemental irrigation. It will grow even bigger with added moisture. Thick textured grass blades, it will rival pampas grass for size and beauty, although it plumes are near as showy, giant sacaton has a flowing fountain appearance. A warm season grass, it is cold hardy and thrives in sun and heat.

Common Name: Sapphire Blue Sea Holly

I am unable to correctly identify the species of ‘Sapphire Blue’ sea holly. I have found references with it shown as a variety or hybrid cultivar of E. alpinum, E. maritimum, E. amethystinum and E. x planum. If you’re looking to order this plant, anyone of the species will produce a plant that looks similar to the picture. This sea holly is named more for its steel blue foliage, than for the color of the flower. Sea hollies make an excellent cut and dried flower and make a stunning architectural display in the garden.

Common Name: Mock Orange, 'Natchez'

Mock orange is one of those versatile old garden shrubs you can place almost anywhere; it will even flower in deep shade. Fragrant single pure white flowers in spring that may reoccur in the fall with a much lesser show. Drought tolerant once established. The versatility and fragrance must certainly be the reasons gardeners choose mock orange, it certainly isn’t for its irregular shape. I’m afraid I haven’t shown it much respect, allowing its mostly shady corner to be littered with gardener’s menagerie of plastic pots and unused brick-o-brack.

Common Name: Prairie zinnia, plains zinnia, desert zinnia, mountain zinnia

Not our old fashioned garden zinnia.  Zinnia grandiflora is the native zinnia for most of the Midwest, West and Southwestern parts of the United States. So widespread a wildflower, each region has named it theirs: plains zinnia, prairie zinnia, desert zinnia and Rocky Mountain zinnia. A terrific low growing and spreading groundcover for poor soils needing no supplement irrigation. Rugged! A survivor without being a pest!

Common Name: Coneflower, Mexican Hat

You can't have just one. As soon as you plant one, you'll have a drift, then a sweep, then a field if you have the space. But I still don't consider the prairie coneflower to be invasive, merely pleasant. Next to the Indian Blanket, the Mexican Hat shouts Southwest prairies. And its a tough hombre. If your stand becomes too dense or too much, just weed some out. They're adaptable to most native soils and will thrive on available or once a month supplementation. Coneflowers bloom yellow, reddish or brown late spring into fall and make an attractive display when mixed.

Common Name: Rose mallow, Texas Star, scarlet rosemallow

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.

 

Common Name: Prairie Dropseed

Prairie dropseed is smaller than both alkali or giant sacaton, more fitting for the city garden. A warm season bunch grass, prairie dropseed is a most attractive low or medium water-use grass with graceful green foliage. The seed heads emerge in late summer into fall with light pink seeds, that is said to naturalize some, but not invasively. A slow grower. Foliage turns a pleasing golden orange in the fall. Native throughout the Great Plains, including Texas. Tolerates most soil conditions.

Common Name: Burgundy Gaillardia, burgundy blanket flower.

Sometimes referred to as Gaillardia x grandiflora ‘Burgundy’.  A cross between G. aristata and G. puchella. I’ve not been able to determine whether these are 2 different varieties, or just name confusion. They must be quite similar, nonetheless. It reseeded once for me, so I'm not sure at all. Medium water for this plant through the heat of summer will prolong blooms, as will afternoon shade. A stunning plant and prolific bloomer for your border.
