Stoplights Hesperaloe parviflora is one of our two newest dwarf Hesperaloe selections. Where most Hesperaloe can easily outgrow tight areas, Stoplights is a compact, yucca-like succulent with soft, green leaves that maintains a mature size of under two feet tall and wide. Three-foot-long crimson-red stalks rise from the center of Stoplights in spring through summer, with the same crimson-red tubular-shaped flowers, which are a favorite of hummingbirds and many pollinators. Stoplights Hesperaloe thrives in poor soils, and hot, arid climates.
