Yellow
The color yellow or closer to the color yellow than other colors.
Native to a large part of North America, golden rod is a pleasant addition to your native garden, and contrary to popular myth, does not cause allergies; the pollen is too heavy to be wind born. But choose a variety of Solidago that does not have invasive rhizamatous roots for lower maintenance.
Attracts bees and butterflies.
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.
Native evergreen shrub that makes an excellent hedge plant and wind break. Its blue-green prickly leaves keep the unwanted out (to a point). Please allow room for its spread.
A habitat plant for shelter and as a food source of food for birds and other wildlife that is an attractive addition to the home landscape, where an evergreen shrub is called for in a sunny spot. Sun yellow flowers in March. Cold hardy to -20°, algerita can be found growing from 4000 to 7000 ft. in elevation in Texas, the southwest and Mexico.
Elegant and stately desert perennial. Soft light blue green leaves. Stalks can tower above desert shrubs to 5-6 feet, but usually 2-4 feet, with racemes of yellow flowers similar to cleome or spider plant flowers in springtime. Requires excellent drainage and lean soils. Thrives on selenium rich soils. Native to canyonlands in SW U.S.
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.
Littleleaf mountain mahogany is the shortest of the mountain mahoganies usually sold. Small, narrow, leathery looking evergreen leaves on many intricate branches. Small yellow flowers in springtime and feathery seed plumes in the fall. The shrub is densely branched and slow growing.
Dark green, semi-evergreen aromatic leaves are the feature most prized, along with the tiny yellow daisy-like flowers that bloom spring to fall. Damianita prefers full sun and lean soil and does well in heat and temperatures to zero degrees. Daminaita will lose its leaves in cold winters.
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.
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.
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.
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.
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.
Small but tough is Perky Sue. Woody base with thin short green leaves from which many stems shoot up to display many yellow daisy like flowers from April into fall. Many people know this plant by the genus name Hymenoxys, but has been changed to Tetraneuris in the last decade. There are a few relatives that look quite similar and are all equally valuable in the garden: T. acaulis and T. odorata.
Mahonia repans is one of my favorite plants with four seasons of interest. Low growing and spreading evergreen shrub is native throughout the Rocky Mountains. Bright yellow berries in spring are followed by black berries in summer and reddish winter foliage. The leaves are thick, glossy and holly shaped. Creeping Oregon grape holly prefers amended, humusy soil that replicates its native habitat as an understory plant in woodlands, but is low water-use once established. It will spread to cover an area, but not invasive. Very attractive!
Many Aquilegia’s are native to the U.S. Golden columbine, Aquilegia chrysantha is a Texas and southwest native, has yellow flowers and can take more sun than some varieties. McKana's Giant is the hybrid columbine most often sold. Large beautiful bi-colored flowers dazzle in woodland and shady area. Rocky Mountain columbine, Aquelegia caerulea; and wild columbine, A. canadensis, are other common columbines. Rocky Mountain columbine is the state flower of Colorado.
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.
Oregon grape holly is an evergreen holly-like shrub native to the Pacific Northwest Rockies down into California. Upright, it is slow growing but can reach a height of 8 feet. Best when grown in shade, especially out of afternoon sun. Prefers a more humusy soil but will only required once a month watering when established, however, can also be placed in medium and high water-use areas. Bright yellow flowers in spring, followed by dark blue berries in summer. The thick, glossy, holly-like leaves have spines at the points. Leaves turn from green to red in winter.
Old fashion garden and English cottage garden herbaceous perennial that works well in the Southwest Cottage Garden. Hollyhocks are considered to be either a biennial or perennial. They produce copious seed but are not considered invasive or troublesome. Plant seed in the fall, or early spring. Avoid watering the foliage if irrigating, a drip system works better that above ground sprinklers.
Another tough and pretty wildflower that populates a wide area from the plains of Oklahoma down to the Chihuahua Desert and over to Colorado and Utah. Leaves are lower near the base of the plant from which stems emerge and bloom in late spring to early summer. Yellow rays with a red to brownish center.
Three leaf sumac is medium height woody shrub native to the Texas Panhandle and throughout the Southwest. Three distinctive cleft and lobed leaves (trifoliate) are medium to dark green. Small greenish yellow flowers in spring are followed by tart red berries in summer, which are used to make a lemonade-like drink. The shrub's flowers have a pleasant fragrance, even though it is called skunkbush by some. Beautiful golden and reddish fall foliage. Cold hardy to Zone 4, yet extremely heat and drought tolerant. Prefers sandy and well drained soils.
Native to the Texas Panhandle, the south and into northern Mexico. Strong chocolate scent fills the morning air. Xeric herbaceous perennial with a deep taproot. Flower closes up during the heat of the day, staying open during more moderate days. Good choice for naturalizing. Best to keep soil on the lean side, will grow leggy in amended soil. Reseeding profusely. Cut back flower to base at end of June if it becomes too leggy. Within weeks, it'll grow back and begin flowering again.
Shadscale lives in alkaline caliche soil in most of its native range throughout the Southwest and has a high tolerance of saline or sodic soils. Given improved soil conditions, it will grow larger. Do not improve the soil to insure it keeps its neat, compact shape. Shadscale blooms yellow flowers in early summer which mature into seed heads. Its silver-gray leaves are semi-evergreen.
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.
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.
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.
