About
Adenium, popularly known as the Desert Rose, is a caudex-forming member of the family Apocynaceae native to the arid regions of eastern Africa and the Arabian Peninsula; the best-known species is Adenium obesum. It stores water in a swollen, bottle-shaped caudex at the base of the trunk to endure long dry seasons, and during the growing season it produces showy funnel-shaped flowers in pink, red, or white. The glossy oval leaves cluster at branch tips and are shed during dormancy. Because the caudex thickens relatively quickly even from seed, Adenium is one of the most popular entry-level caudex plants, and extensive cultivar breeding is carried out especially in Thailand. It thrives in full sun and requires a very free-draining mix of materials such as akadama and pumice. Water generously when the soil dries during growth, then reduce watering or withhold it entirely during the leafless dormant period. Cold tolerance is low, so it should be kept in a bright frost-free room in winter. The sap is toxic and should be handled with care.
