A group of tropical plants belonging to the dogbane family, native to Africa and Asia. Seeds of the handsome climber Strophanthus gratus and Strophanthus kombe yield a poison, strophantin, which is used on arrowheads in hunting, and in medicine as a heart stimulant.
These frost-tender plants prefer a protected, part-shaded position and fertile, humus-rich, moist but well-drained soil.
Exotic species of Strophanthus:
Strophanthus petersianus - Sand Forest Poison Rope, scrambling shrub, creamy white flowers, pinkish red on outside, dangling petal lobes.
