Swanplant (Gomphocarpus fruticosus, also known as Asclepias fruticosa) is an upright shrubby perennial from the Asclepiadaceae plant family. It is native to Africa, and the southern parts of the Arabian Peninsula. It produces balloon-like or curved green fruits, which are covered in soft bristles. Each fruit contains numerous seeds topped with silky white hairs.
All parts of the plant, particularly the stems, contain a white milky sap (latex) which is made up of toxic cardiac glycosides.
