Adenium obesum is actually a succulent member of the Oleander family. It originates in East Africa, from regions where it rains frequently in the summer, but is very dry in winter.
Blooming time: Spring, and a second time in September.
Culture: Desert Rose needs to have a soil mix of sand or brick chips mixed into regular soil, or a cactus mix. The soil should dry completely between waterings. For this reason clay pots are better suited for growing Desert Rose than plastic pots. Water sparingly during winter months.
Propagation: Desert Rose can be grown from seed or cuttings. The best time for either method is in the spring.
Seed: Scatter seed into a mixture of sand/soil. Seeds germinate easily, and seedlings grow without any special attention.
Cuttings: Propagation by cutting is easy. Cut end shoots and let dry for a day or two. Be careful of the toxic sap. Stick shoots into a pot of moist soil, and provide bottom heat. Keep soil moist.
All parts of Desert Rose are poisonous and should be kept out of reach of children and animals.
