Gomphocarpus physocarpus |
Syn. Asclepias physocarpa
Native Region: South Africa, Zimbabwe

Preferred Climate: tropical
Harvest Date: Sunday 13 August, 2023
Seed count: 20-25
Description:
This plant belongs to the milkweed family, and like all milkweeds they attract the lovely Monarch butterfly to the garden. This deciduous sub-shrub is often grown as an annual. It has sticky, hairy stems and narrow lance-shaped grey/green leaves. In summer 2-inch cymes of creamy white flowers each about 1.5-2 cm (1/2-3/4 inch) across appear. The flowers are followed by balloon-like fruit, about 4-5 cm (2-2.5 inches) across, translucent lime-green and often spiny. The seedpods' inflated appearance gives rise to a number of humorous common names, although we tend to favour 'Swan Plant'. The plant grows to 4-6 feet tall and 2 feet wide.
