Notes
Glade mallow (Napaea dioica) is a tall perennial for rain gardens, wet borders, and back-of-the-bed screens. It is hardy to USDA zone 3, or down to -40°F (-40°C). This plant likes part sun or part shade and wet soil. Stems reach up to 9 feet and branch near the top. White flowers crowd into large clusters from early to late summer. The big round leaves are cut into coarsely toothed lobes.
