Kniphofia (Template:IPAc-en,[1] Template:IPAc-en,[2][3] Template:IPAc-en[4]) is a genus of perennial flowering plants in the family Asphodelaceae, first described as a genus in 1794.[5] All species of Kniphofia are native to Africa. Common names include tritoma, red hot poker, torch lily and poker plant.

Description

The genus has herbaceous and evergreen species. The herbaceous species and hybrids have narrow, grass-like leaves Script error: No such module "convert". long, while evergreen species have broader, strap-shaped foliage up to Script error: No such module "convert". long. All plants produce spikes of upright, brightly coloured flowers well above the foliage, in shades of red, orange and yellow, often bicoloured.[6] The flowers produce copious nectar while blooming and are attractive to bees and nectar-feeding birds such as sugarbirds and sunbirds.[7] In the New World, they may attract nectarivores such as hummingbirds and New World orioles.

Taxonomy

The genus Kniphofia was first erected by Conrad Moench in 1794.[8] Moench considered the species he was describing (now Kniphofia uvaria) sufficiently different from Carl Linnaeus's genus Aletris and from Veltheimia to warrant a new genus.[9] The name honours Johann Hieronymus Kniphof, an 18th-century German physician and botanist.[10]

Species

since February 2025Template:Dated maintenance category (articles)Script error: No such module "Check for unknown parameters"., Plants of the World Online accepted 73 species, including two hybrids.[11]

Cultivation

Several species of Kniphofia are cultivated as garden plants, valued for their architectural properties. These include K. galpini, K. northiae, K. rooperi and K. thomsonii.

In addition to the species, many named cultivars of mixed or uncertain parentage have been selected for garden use. The following have gained the Royal Horticultural Society's Award of Garden Merit:-[13]
