Eastern Rose Mallow
Hibiscus moscheutos, commonly known as hardy hibiscus or swamp rose mallow, is a vigorous, sturdy, rounded, somewhat shrubby, hairy-stemmed, woody-based perennial of the mallow family that loves wet areas such as marshes, swamps, floodplains, river banks, moist meadows, and moist woods. Showy, dinner plate-sized, hollyhock-like flowers (each to 4-6” diameter) have five overlapping white, creamy white or pink petals with reddish-purple to dark crimson bases which form a sharply contrasting central eye.
Tolerates some light shade, but full sun with good air circulation produces the best flowers, the strongest stems and the best environment for resisting potential diseases. Site in locations protected from wind to minimize the risk of wind burn. Pinch back growing tips when they reach 8” and again at 12” if bushy plants are desired. Cut back stems to approximately 3-4 inches in late autumn.
