About
Scadoxus multiflorus (formerly Haemanthus multiflorus) is a species of bulbous plant native to most of sub-Saharan Africa from Senegal to Somalia to South Africa. It is also native to Arabian Peninsula (Saudi Arabia, Yemen, Oman) and to the Seychelles. It is naturalized in Mexico and in the Chagos Archipelago. It is grown as an ornamental plant for its brilliantly coloured flowers, either in containers or in the ground in where the climate is suitable. There are three recognized subspecies. Strongly toxic like other Scadoxus species, it has been used as a component of arrow poisons and fishing poisons, as well as in traditional medicine. Common names, some of which are used for other species, include blood lily, ball lily, fireball lily, blood flower, Katherine-wheel, oxtongue lily, poison root and powderpuff lily.
How to grow it
Scadoxus multiflorus is chill-sensitive and must be kept at a minimum temperature of 5 °C (41 °F), for forms of southern African origin, up to
10 °C (50 °F) or more for those of tropical origin. An open, well-drained growing medium, largely organic in nature, is recommended. Propagation is by seed. Pests are those of Scadoxus generally.
Safety
The genus Scadoxus has some strongly toxic species, containing poisonous alkaloids lethal to animals, such as sheep and goats, that graze on the leaves or bulbs. Scadoxus multiflorus is traditionally used in parts of tropical Africa as a component of arrow poisons and fishing poisons. It is also used in traditional medicine, although in South Africa less so than Scadoxus puniceus.
Where it grows
The species is native to tropical and southern Africa and parts of the Arabian Peninsula. The subspecies S. m. subsp. multiflorus is found throughout southern Africa. S. m. subsp. longitubus is found across tropical West and Central Africa, including in Cameroon, Ghana, Ivory Coast, Liberia, and Sierra Leone. S. m. subsp. katherinae is native to Mediterranean climate forest, scrub and woodland in eastern southern Africa – Cape Province and KwaZulu-Natal in South Africa and Swaziland. It is primarily a plant of moist, shady habitats, including savannah woodlands and forests along rivers and mountains.
