Grow in average, medium moisture, well-drained soils in full sun. Prefers rich, humusy soils. Intolerant of wet, heavy soils. Locate in areas protected from wind. Promptly remove spent flower spikes. Crowns benefit from winter protection in USDA Zones 5 and 6 (mulch or tie leaves together forming a canopy over the crown so as to prevent water from settling on the crown and freezing). Established clumps are best left undisturbed.
Kniphofia uvaria, commonly known as red-hot poker or torch lily, is an upright, clump-forming, rhizomatous perennial that is native to South Africa. From an 18-24" tall basal tuft of coarse, linear, sword-shaped, semi-evergreen, bluish-green leaves (to 3' long and 1" wide) arises a succession of thick, naked flower scapes (typically to 3-4' tall) with dense terminal racemes (6-10" long) of drooping, tubular flowers. Buds and emerging flowers are red but mature to yellow, giving each spike a two-toned appearance. Flowers bloom from late spring to early summer.
