Rose mallow is a Missouri native plant which typically occurs in wet soils along ponds and sloughs, in ditches or in wet woods, sometimes forming large colonies. A vigorous, erect, often woody-based perennial that typically grows 4-6' tall (infrequently larger) and features showy, hollyhock-like, 5-petaled, white or rose flowers (4-6" diameter) with magenta-crimson eyes. Flowers are borne in the upper leaf axils. Each flower has a prominent and showy center staminal column. Perhaps the largest flower of the native Missouri wildflowers. Long, mid-summer to fall bloom period. Ovate, serrate leaves (to 6" long). Leaves, stems and fruit capsules are distinctively hairy (lasiocarpus from Greek meaning hairy-fruited).
A large plant for the rear of the perennial border, mixed border, native plant garden or patio area or courtyard. Also effective when grouped in moist locations such as along the edge of a pond or stream. (info source: missouribotanicalgarden.org)
