Main blooms primarily during the months of June, July and/or August.
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.
The flowers of Salvia darcyi are similar in appearance to Salvia greggii, however the shrub itself is more herbaceous than shrubby. I know of no common name for S. dacryi. Some sources say it is cold hardy to Zone 7, however it thrives in Denver Botanical Garden’s Zone 5. S. darcyi is native to the mountains of Northern Mexico and will do well in amended soil. Hummingbirds love it.
I have it planted in my xeristrip for a number of years. It will flower more vigorously with irrigation everyother week, when needed during hot drought years.
The Arizona rosewood is classified either as a quite tall shrub or short to mid height tree. One of it's best features is that it is evergreen, with slender glossy green leaves approximately 3 inches long. It puts on small white flowers in summer. One of the few drought tolerant, native, evergreen trees available in the trade. Slow growing.
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.
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.
There are several varieties of Salvia guaranitica that range in shades of blue from light to dark. As with most of the tube-shaped salvia flowers, S. guaranitica is a hummingbird magnet.
Native to South America, S. guaranitica is not zoned cold hardy for the Texas Panhandle, but it has wintered over in protected Amarillo gardens in many locations for many years. It has wintered over for me at least 5 years, unprotected. Deadheading is not required.
Arizona rosewood is one of the few native evergreen trees or tall shrubs that are low water-use. Underused in the Texas Panhandle, mostly due to lack of availability. But with searching in Albuquerque or Santa Fe, one should be able to locate a specimen. Faster growing than the Chisos rosewood. Long slender, serrated, glossy green leaves with white flowers in summer.
Texas, or scarlet sage is a perennial to the Southern U.S. and Texas. In the Texas Panhandle, it is sold as a bedding plant, since it is not cold hardy. Some varieties will come back due to re-seeding. Many varieties are available, some are more drought tolerant than others, such as 'Forest Fire', while 'Lady in Red' requires medium water-use beds. Summer long blooming, choose your color among scarlet, red, rose, pink, coral and white. As with most sages, hummingbirds, butterflies and bees are attracted to them.
This native shrub should be used alot more in our area. Drought tolerant shrub. If planted in a moister area it is important to have good drainage. Attractive and pleasantly fragrant fern-like foliage. The tiny white flowers with yellow centers that appear towards the end of the branches in June should be clipped in fall to late winter for better appearance. It is said the deer do not browse fernbush. Semi evergreen, it does loose its leaves in Amarillo. Reputed to be cold hardy to -25°.
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.
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.
Purple or desert sage prefers leaner, quick draining soils. It is said to grow 2-3 feet tall and deeply branched with silver gray foliage and a profusion of violet bluish flowers atop spikes in late spring and summer. Low water-use, but does better with once a month irrigation. One of the finest flowers of the desert, it is the sage of Riders of the Purple Sage, by Zane Grey. Grows throughout the Great Basin Desert.
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.
Unlike, S. nemorosa ‘May Night’, I don’t mind deadheading this salvia, perhaps because of its plum color it does not require as persistent deadheading. Notice the gray-green leaves of ‘Plumosa’, versus the green leaves of ‘May Night’. The stems tend to flop, but the flower stalks continue to grow and flower upright -- very strange.
Big Bend silverleaf is the most cold hardy of the Leucophyllums and has wintered over in Amarillo, Zone 7, for 5 years so far. Possibly cold hardy to Zone 6. It is hard to beat a more attractive summer blooming shrub for small xeric spaces. After summer rainfalls, Big Bend silverleaf, native to the Big Bend National Park area, becomes covered in silver blue flowers that twinkle like jewels among its silvery gray leaves. Hard to find, it's worth searching for.
Western ironweed is a prairie native to the Great Plains states. Mid-summer to fall deep purple flowers clusters appear at the top of stalks. Ironweed can be invasive, rooting madly down to a foot so control could be difficult. Drought tolerant and cold hardy for the right location.
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.
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'
Agaves are striking and architectural Southwest native plants and are included in a group of plants I term Southwest evergreens. They are unusual in that at maturity, they only flower once, and then die. for this reason, some classify them as multiannual, rather than perennial. However, as they common name suggests, it takes many years before they flower. Leaves of the Agave are arranged in a spiral beginning from a near invisible stem, forming a rosette.Agaves vary in size from 4-6 inches to larger than man-size.
White flowering zinnia is native to the Southwest and Northern Mexico. A low mounding plant, it becomes completely covered with small white flowers with a central yellow disk, similar to our native prairie zinnia, Zinnia grandiflora. Blooms from June through fall. Desert zinnia is toxic if ingested by humans.
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.
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.
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.
Sand lovegrass is a warm season bunch grass typically found in sandy soils east of the Rockies over a wide range of the U.S. The grass clumps themselves are usually 12-18" tall with the plumes rising to 3-4 feet. Will grow in clay and poorer soils. Very pleasing wispy, arching habit with a soft sway and rustle in the wind. Can grow in partial shade. Seed heads are somewhat purple, fine textured. Will reseed. Low or no water-use.
Typically a Zone 8 plant, the Christmas holiday bulb, Amaryllis, has been successfully wintered over in Amarillo, specifically, the Wolflin area in this case. If you have a warmer, protected micro-niche, try planting your seasonal Amaryllis outdoors, and leave it there well mulched over winter. I 've winter over Amaryllis in my backyard, but it hasn't reliably bloomed. It requires a full sun location and well amended soil to soak up nutrients to be stored in the bulb.
