This native southeast African plant is a wonderful butterfly plant. Its clusters of white flowers are insigificant but the light green balloon-like seed pods make it a great plant for a border and as a cut flower. It can be an agressive self seeder so care should be taken. It is most commonly sold as Asclepias physocarpus.
