Kniphofia /nɪpˈhfiə/,[1] also called tritoma, red hot poker, torch lily, knofflers or poker plant, is a genus of flowering plants in the family Xanthorrhoeaceae, subfamily Asphodeloideae,[2] that includes 70 or more species native to Africa. Herbaceous species and hybrids have narrow, grass-like leaves 10–100 cm (4–39 in) long, while perennial species have broader, strap-shaped foliage up to 1.5 m (5 ft) long. All plants produce spikes of upright, brightly colored flowers well above the foliage, in shades of red, orange and yellow, often bicoloured.[3] The flowers produce copious nectar while blooming and are attractive to bees. In the New World they may attract sap-suckers such as hummingbirds and New World orioles.

The Kniphofia genus is named after Johann Hieronymus Kniphof,[4] an 18th-century German physician and botanist.
