Impatiens glandulifera candida

Lovely, pure white, “Policeman’s Helmet” flowers are held on multi-branching stems on this rare Impatiens species. It gets tall -- to 4’ and bears serrated, 6” long leaves. The seed capsules are explosive when touched, catapulting the seeds at least 3 feet. Reseeds! (Though seedlings are easy to pull out).
