Incredible rose-scented foliage with deep purple flowers. Very rare in cultivation - this was a gift from Holly Shimizu at the U. S. Botanic Garden. An article in Mother Earth News Magazine a couple of years ago touts this as a great mosquito repellant, along with Citronella Grass, Catnip, Sacred Basil, Citrosa Geranium, and Lime Basil. Extremely hardy.
