  • Biogeography
    • Native Distribution :

  • Description & Ethnobotany
    • Plant Morphology :
      Growth Form: Succulent shrub with a swollen base known as a caudex.
      Foliage: Smooth, glossy green leaves are obovate with entire leaf margin and truncate or rounded leaf apex. Leaves are spirally arranged.
      Flowers: Flowers are tubular with 5 oval-shaped lobes that are flared and perpendicular to the floral tube axis (known as salverform).
      Cultivation :
      Although this species is commonly known as 'Desert Rose', it grows well in tropical, humid climates. Insects are generally not a problem, but be careful of scale insects, mealy bugs and spider mites. Fungal and bacterial stem or root rot cause serious damage that is difficult to treat. Infected plant parts should be removed immediately. To obtain a plant with a swollen base (caudex), the plant needs to be propagated from seed and not by stem cutting.
      Ethnobotanical Uses :
      [Others]: In Africa, tribal peoples apply the toxic milky latex of this species to arrows.
