I grow three supspecies of Impatiens capensis. The first is from Wisconsin, has clear green stalks and orange yellow flowers. The second is the Pacific NW native with swollen red leaf joints along the stems and dark orange flowers. The Third is on from South Carolina I call 'doublewide'. Doublewide blooms late in September, and grows to 8' tall with double size leaves. It has pale orange flowers.

At their peak, I. capensis leaves and stalks appear translucent chrysalis green with the little orchid shaped flowers hanging like jewels. Self sows and forms drifts in wetlands and ditches. In the garden thin seedlings to 36" apart and plants will form impressive bushes. Children love to search for and touch the seed pods to send the seeds flying.
