Heart vine - Heart vine

Japanese: ハートカズラ - はーとかずら
Heart vine - Heart vine

A perennial plant of the genus Ceropegia in the family Asclepiadaceae (APG classification: Apocynaceae). Native to South Africa. The underground part becomes a fleshy tuber, and the bulbil also grows at the node partway up the stem. The thin stem grows long and has heart-shaped leaves that grow opposite each other. The name comes from this leaf shape. It looks elegant when grown in a hanging pot with the long stems hanging down. It is drought-resistant and can survive winter as long as it does not freeze.

The genus Ceropegia has over 150 species distributed in tropical Asia, Africa, Madagascar, etc. Climbing species include Amanojaku ( C. haygarthii Schlecht.) with large flowers and Suiryu ( C. sandersonii Hook.f.) with large flowers. There is also Usugumo ( C. stapeliiformis Haw.) with a fleshy stem that does not form a vine.
