Culture
Easily grown in dry, sandy, sharply-drained soils in full sun. Thrives in hot, dry, desert conditions, but is also surprisingly winter hardy to USDA Zone 5. The key to growing this plant well is having superior soil drainage. Excellent heat resistance and drought tolerance. Will self-seed in the landscape. May be propagated by clump division. Tolerates urban conditions.
Noteworthy Characteristics
Hesperaloe parviflora, commonly known as red yucca, coral yucca, hummingbird yucca, redflower false yucca, and samandoque, is a yucca-like evergreen perennial succulent. It is native to the Chihuahuan desert in western Texas south into northeastern Mexico where it is typically found growing in desert areas, prairies, rocky slopes, and mesquite groves. Narrow, arching, sword-like, blue-green leaves (2-3’ long but only 1” wide) grow in basal clumps to 3-4’ tall spreading to 6’ wide. Although the leaves are evergreen, they often acquire purple or reddish-bronze tints in cold winter climates. Each leaf has distinctive thread-like marginal hairs. Red to pink tubular flowers in branching inflorescences rise well above the foliage clump on red flower stalks to 4-6’ tall. In cold winter climates, flowers bloom in early to mid summer with frequent rebloom into fall, but in warm winter climates plants often bloom earlier with continued bloom occurring throughout much of the year. Excellent hummingbird plant.
Genus name comes from the Greek word hesperos meaning western in reference to the plant being native to North America (in the West) and aloe in reference to the plant somewhat resembling plants in the genus Aloe.
Specific epithet comes from the Latin parva meaning small and flora meaning flower in reference to its small flowers.
'Coral Glow' is a compact selection of redflower false yucca that features airy, gently arching flowering stalks up to 6' tall held above clumps of narrow, evergreen basal foliage. The small, tubular flowers have coral-red exteriors with light yellow interiors and can reach up to 1" long. Very attractive to hummingbirds. This selection does not tend to set seed. 'Coral Glow' is the result of a cross between a yellow-flowering form and a red-flowering form of H. parviflora. Plant patent number PP29626 applies to this cultivar.
Problems
No serious insect or disease problems. Deer like to feed on the unarmed foliage and flower spikes. Aphids often appear when flowers are in bloom. Watch for scale.
Uses
Desert gardens, rock gardens, path margins. Also can be massed for enjoyment of its long summer bloom. Good large container plant.
