This family includes thousands of species with genera that are very different from one another: Hoya, Caralluma, Cynanchum, Echidnopsis, Huernia, Tavaresia, Ceropegis, Stapelia etc.
A peculiarity of the latter is that the pollination is carried out by meat flies since the flower emits a stench of putrid meat.
These plants originate in various places:
- Northern Africa for certain Caralluma
- Southern Africa for certain Ceropegia
- Canary Islands for other Ceropegia (e.g. Ceropesia fusca)
- Madagascar for Cynanchum
- Ethiopia and Somalia for certain Echidnopsis
- Arabia and Tanzania for other Echidnopsis
- Southern Africa for certain Hoodia and Huernia
- China and Australia for Hoya
- South America and Kenya for other varieties of Huernia
These plants generally need little water and do not live in full sunlight.
Here they do not need water in winter when its very cold, nor in summer when its very hot. Naturally each plant its specific care.
