Average Garden Soil
Native Texas Panhandle soils amended with between 2-4 inches compost or other organic and/or amendments.
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.
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.
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.
New Mexican privet can be viewed either as a tall shrub or smaller tree. New Mexican privet will flower (tiny yellow) before leafing out with small oval glossy green leaves to be followed with black berries in the fall. Heat and drought tolerant will live in most soils and water-use areas. Attractive taller plant for the home landscape, similar to the yaupon holly in form.
Spring blooming crocus is a favorite among gardeners, heralding the end of winter. Many species of crocus can actually bloom in winter months. I've seen crocus bloom as early as mid Janurary, although February and March are more common. There are many different species of crocus, most people choose them by color, height or bloom period. Their colors range from yellow to purple, lavender, violet and white, some in combination of colors. Commonly, Crocus chrysanthus, C. venus, and C. angustifolius. C.
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.
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.
Grown in the South for decades, most people think of crape myrtle as a native American plant; it is however native to China and Japan. Small tree or large shrub that is cold hardy to Zone 7. I’ve grown the same crape myrtles for over 20 years, but they’re planted close (too close!) to my bricked house on both the northeast and northwest corners. They’ve been stem hardy, not just root hardy, and have grown up to about 10-12’. In most cases, crape myrtle will not grow into tree form in the Panhandle, but there are mature, tree size crape myrtles in Amarillo.
The most remarkable quality of Red Dragon Persicaria is its burgundy red patterned leaves and red stems, a plant grown much more for its foliage than flowers. (The flower stalk in the upper right is of Acanthus spinosus.) Not a native (native to China) it will come back if nipped by a late frost and will suffer sunburn in afternoon sun. Red Dragon may take 3 years before flowering, however, that is not a drawback.
The Crassulaceae family of plants fascinates me, and the sedums are one of its larger genera. I first saw ‘Frosty Morn” featured on a gardening program from Iowa, so I wondered whether it’d be drought tolerant. Shortly afterwards, I found it at our local nursery and planted in my xeristrip. It has never faltered. The only disfiguring occurrence is a little nipping by grasshoppers during early summer, which has never seemed to harm it, or other large leafed sedums.
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.
Solidago rugosa 'Fireworks', arching branches similar to S. canadensis 'Golden Baby', only is low water-use and more golden in color. Fireworks goldenrod will also flower in summer and again in the fall. Makes a great splash in the summer garden.
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.
Yaupon holly is a tall shrub or a small tree growing typically to 8-12 feet in the Texas Panhandle. Cold hardy to Zone 7 (still best to plant in a protected location), it prefers partial shade, especially afternoon shade. Low (once established) to high water use. Small leathery, glossy, evergreen, dark green leaves (to 1.5” long) have toothed margins on dense branching. Insignificant greenish white flowers in springtime followed by red berries in the fall. Female plants require a male plant to pollinate and bear fruit (dioecious). Attractive tall, traditional looking shrub.
Daffodils are the most notable of the spring bulbs. Reliable from year to year, daffodils can be depended upon to bloom even when faced with late season blizzards and are unpalatable to deer and squirrels. Daffodils aren't too particular about soil, but do better in amended soil, planted about 4 inches deep in October to December. Typical bloom times are February through April, depending on the variety, and there are thousands of varieties to choose from.
Desert never equates with drab. The flowers on Desert Bird of Paradise are simply stunning! Though classified as a Zone 7 plant, I’ve grown Desert Bird of Paradise for 3-4 years near a south facing wall and have seen several others around Amarillo, without it dying back it to roots. However, if it does, just prune out the dead wood. Eye catching flowers bloom continually from June into fall and attract hummingbirds. Finely divided green leaves. It is said to survive on 8” of rainfall, but monthly soakings enhance it. C. mexicana, Mexican Bird of Paradise and C.
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.
Sweet pea is another wonderful old fashioned, fragrant annual climber. That is, the original L. odoratus was fragrant; many varieties today have had the fragrance bred out of them to achieve more and bigger blooms and different colors. Sweet pea is versatile and will grow in a variety of water zones and soil types. I have seen it growing alone for 2 years at an abandoned home, alongside lantana. Some gardeners just toss out the seeds in fall or spring and wait to be surprised.
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.
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.
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.
Low water-use non-native hybrid shrub (Artemisia arborescens x Artemisia absinthium) from Europe and Asia. Vigorous grower, do not overwater. Coldy hardy to Zone 6. Ever-silver with elegant finely cut leaves. 'Powis Castle' is named for Powis Castle in Wales. Rarely flowers.

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.
Junipers are native to much of the U.S. and come in many sizes and shapes. Juniperus horizontalis is the low growing and spreading juniper, used mainly as an evergreen groundcover. There are many varieties available, one or more to suit every purpose and location. Colors and heights vary from the common dark green evergreen to blue green, blue and even lime or chartruese. Their hallmark is their fine texture, many of the newer varieties have a pleasant soft touch. Water use can vary as well, but typically, once established many will thrive on once a month deep watering.
Mat daisy is a low growing spring blooming plant. Drought tolerant. Not exactly a groundcover, as the top growth disappears during summer and reemerges as a green basal rosette in fall, getting ready to bloom again in the spring. Blooms late March to May with small white daisy-like flowers that have pink undersides. Forms a compact ground-hugging mat. Will self seed some, but never invasively.
