Adenium is a genus of flowering plants in the family Apocynaceae first described as a genus in 1819. It is native to Africa and the Arabian Peninsula.[3]
Adenium obesum is grown as a houseplant in temperate regions. Numerous hybrids have been developed. Adeniums are appreciated for their colorful flowers, but also for their unusual, thick caudices. They can be grown for many years in a pot and are commonly used for bonsai.

Because seed-grown plants are not genetically identical to the mother plant, desirable varieties are commonly propagated by grafting. Genetically identical plants can also be propagated by cutting. However, cutting-grown plants do not tend to develop a desirable thick caudex as quickly as seed-grown plants.
The sap of Adenium boehmianum, A. multiflorum, and A. obesum contains toxic cardiac glycosides and is used as arrow poison throughout Africa for hunting large game.[4]
