Adenium swazicum Stapf

Adenium swazicum occurs in Eswatini (formerly Swaziland) and adjacent parts of South Africa. The stems tend to be weak and decumbent, and the caudex (actually swollen roots) tends to be underground. Plants flower in late summer and fall (some clones flower most of the year). The best distinguishing character is the petals of solid color (no fading toward the throat), which is darker in color and lacks nectar guides. In addition, the anther appendages are very short and hidden within the tube.  A. boehmianum is the only other species that shares these floral traits. The 2 species are distinguished by growth form: swazicum is a lax shrub while boehmianum is erect and usually arborescent. White flowers occur in cultivation.

A. swazicum 'Perpetual Pink'. This clone is a more sturdy plant than is typical of the species, and it flowers year-round.

Note: A. swazicum is becoming rare and difficult to find because it is extensively collected by local people for medicine. I would love to post more photos of this plant in the wild. If you have any, please contribute photos and a description using this form. Due credit will be given.
