Another species of red-hot poker, Kniphofia nelsonii, was featured on BPotD last year. Kniphofia northiae is a brute in comparison; the inflorescences are roughly twice as large, and the leaves more closely resemble those of Agave instead of the grass-like foliage of Kniphofia nelsonii (image search). It is with good reason that the common name for this plant is giant poker or giant red-hot poker (though I’ve seen one reference call it octopus red-hot poker).
Kniphofia northiae is found in South Africa, the centre of diversity for the genus. However, the genus is more broadly distributed throughout continental Africa. Species can also be found in Madagascar and Yemen.
