Cultivation and uses
Adenium is a popular houseplant in temperate regions. It requires a sunny location and a minimum indoor temperature in winter of 10 °C. It thrives on a xeric watering regime as required by cacti. Adenium is typically propagated by seed or stem cuttings. The numerous hybrids are propagated mainly by grafting onto seedling rootstock. While plants grown from seed are more likely to have the swollen caudex at a young age, with time many cutting-grown plants cannot be distinguished from seedlings. A houseplant is usually a tropical or semi-tropical plant that is grown indoors in places such as residences and offices. ... Deserts and xeric shrublands is a biome characterized by a dry climate. ... This article is about the desert plant. ...
The plant exudes a highly toxic sap which is used by some peoples, such as the
Akie in
Tanzania, to coat arrow-tips for hunting.
