Giant swan plant
Gomphocarpus physocarpus or the ‘GIANT SWAN PLANT‘. More robust, and more resistant to the onslaught of the caterpillars, much more resilient than the swan plant (G. fruticosus). When identifying the two plants, the main difference is that the seedpod of G. physocarpus is not swan-shaped (although it’s often called the giant swan plant) but has round seedpods. The leaves are shorter and wider, and the plant will grow to 2-4 metres, whereas the swan plant reaches 1-2 metres.
Sow directly in the garden when soil is warmer. For earlier sowings use seed mix in egg cartons (or similar) and cover with a light sprinkling of topsoil. Keep moist and warm. Transplant when seedlings are 5-10 cm tall.
The seeds USED to be classified as Asclepias physocarpa and A. fruticosa, but the plants were reclassified in 2001 as part of the African family of milkweed, Gomphocarpus.
