Kniphofia

Kniphofia Moench

Kniphofia is a genus with ca. 70 species, all distributed in Africa (incl. Madagascar) and Arabia (Mabberley 2008, Ramdhani & al. 2009). Its center of diversity lies in southern Africa. About 11 species and numerous cultivars and hybrids are cultivated as ornamentals (e.g. Droop 1986, Jäger & al. 2008, Whitehouse 2010). Several of these have been recorded as escapes or established throw-outs (see e.g. Stace 2010 for the British Isles or Conran 1987 for Australia). A single taxon, Kniphofia ×praecox Baker, is also known from Belgium.

Molecular studies have confirmed that most of the species in the wild hybridize with each other, blurring the boundaries (Ramdhani & al. 2009). In cultivation only the most distinctive species can be named with any degree of certainty (Whitehouse 2010). It is very probable that pure species are almost no longer present in cultivation (Jäger & al. 2008).
