First described by Hans Schinz in 1892, belonging to the Passifloraceae family. It is from the southern Africa and Botswana, and can get op to one meter or more in diameter! The branches reach for up to three meters. It prefers acid, mixed soil, well watered in the summer and can dry out in winter. Keep out of strong sun. The flower is green/crème in colour. It can be reproduced both by cuttings and by seeds. The cuttings might not form a caudex!
Dioecious, I don't know what I got. If its a female, and I get it pollinated, it will get fine orange fruits. The sap is poison, and the plant can't stand frost.
Its named after the Yemen city of Aden.
