Haemanthus is a genus of twenty-two recognized species discovered within the very southern a part of the continent, within the nations of South Africa and Namibia (species from additional north which have traditionally been included in Haemanthus at the moment are handled as a separate genus Scadoxus). It’s a member of the belladonna household Amaryllidaceae and, like many different members of that household, grows as a herb from a fleshy bulb that’s partially or completely hid underground. The plant above floor could also be annual or persistent, relying on species. Every particular person Haemanthus plant produces only a few leaves at a time: two is the most typical quantity (Van Jaarsveld 2020). The leaves are roughly fleshy, typically furry, and could also be directed upwards or unfold outwards.
In these species that shed their leaves, flower stalks are produced earlier than the following season’s leaves seem, in the same matter to the associated bare women Amaryllis belladonna. Flowers are produced in dense umbels, subtended by bracts which are typically brightly colored, so at a look the inflorescence of some species is perhaps taken for a single massive flower as much as ten centimetres in diameter. Relying on the species, the supporting stalk could fluctuate from over a foot in top to just a few centimetres. The primary species to be described bear flowers of a vivid crimson color, explaining each the genus and vernacular names, however flowers may additionally be pale pink or white. Species that lack the crimson color could also be known as ‘paintbrush lilies’ slightly than ‘blood lilies’. Fruits are smooth fleshy berries.
Phylogenetic analyses of the genus have recognized two main clades, a principally jap clade present in areas with summer season rainfall and a principally western clade related to winter rainfall. A notable outlier is the jap summer-rainfall species H. montanus which is the sister taxon to the winter rainfall clade. Members of the summer-rainfall clade have white or pale pink flowers; members of the winter-rainfall clade have pale pink to darkish crimson flowers. Members of each clades have been grown as pot crops for his or her uncommon look although the scent of the flowers shouldn’t be thought to be nice. Maybe essentially the most broadly grown species is H. albiflos, a species native to each the western and jap components of South Africa that bears flowers in umbels as much as seven centimetres large. This species is evergreen, carrying its leaves year-round.
