Hibiscus grandiflorus (Giant Swamp Mallow)

200 (300)cm, Giant Swamp Mallow is an eye-catching, yet still rarely cultivated perennial herbaceous shrub from wet areas in south-eastern USA (Florida). It makes very tall annual stalks with very large, always pale rose flowers, which is the typical and only color in this species. Additionally, petals are narrower than in any other North American swamp mallow species. Leaves are palmately-divided, greyish-green, and smoothly pubescent. The annual stalks usually die down in winter and the plant re-sprouts in following spring. For any very humus rich, always slightly moist soil in full sun. During winter cover the dormant rootstock with a mulch-layer to give some additional protection from freezing through. Seeds or plants in the garden trade are mostly either Hibiscus moscheutos or some hybrid with an atypical flower color and form. Our seeds are from true-to-type plants. VII-IX.
