About Kniphofia uvaria (Red Hot Poker)

Kniphofia uvaria, or Red Hot Poker, is an herbaceous perennial most recognized by its long bright flowers. From late spring through early fall, up to 8″ tall flower spikes emerge in red, yellow and orange colors. Sitting atop stems that together can reach up to 3′ tall each bloom can last up to 18 days, much longer than most flowers. Its grass-like green foliage reaches an average landscape size of 1.5-2′ tall and wide and grows at a fast pace, reaching its full landscape size within 1-1.5 years.

Planting and care instructions

Both easy to grow and maintain, a Red Hot Poker should be planted in an area that receives full sun using well-draining soil. Water regularly after planting to establish healthy roots then reduce frequency. Be sure to let the topsoil dry out before its next watering. Once established, this plant can tolerate drought conditions. To keep a clean appearance, cut spent blooms. If desired, a general fertilizer can be used in the spring before new growth begins.

Landscape design ideas

Kniphofia uvaria is a practical choice for landscape areas prone to wildfires and drought conditions. Plant in multiples for a dramatic effect and be sure to take advantage of this plant’s repeat blooming for regular fresh cut flowers.
