Glade Mallow
Napaea dioica
The only species in its genus and the only North American mallow with separate male and female plants — a huge Midwestern perennial with maple-like leaves up to two feet wide and airy panicles of small white flowers on eight-foot stems. Male plants flower more showily. A river-bottom and wet-prairie species, uncommon in the wild and unmistakable in a garden.
