Rose Mallow

The Rose Mallow (Hibiscus moscheutos) is a dazzling herbaceous perennial that delivers dinner-plate-sized blooms in midsummer that stop garden visitors in their tracks. This hardy beauty sports huge, tropical-style flowers in varying shades of white, pink, or red, often with a contrasting eye!

Its blooms are slightly fragrant with a light, sweet scent and appear continuously through late summer into early fall, attracting hummingbirds and pollinators in droves. The lush, large green leaves give a bold texture to the garden, while its fast growth ensures a quick impact in your landscape.

Boasting a sturdy, upright growth habit, Rose Mallow reaches a varying size of 3-7 feet tall and 2-4 feet wide. Thick, fleshy stems emerge in spring from a hardy root system, supporting large, heart-shaped leaves with a rich green hue. In autumn, foliage may take on golden tones before frost. Once established, the plant forms a dense, shrubby clump, with each stem topped by massive blooms that can measure up to 10 inches across.
