Glade Mallow

About Glade Mallow

Glade Mallow is a majestic and rare giant of the Midwest, standing as the only member of its genus and a truly unique addition to the native garden. This impressive perennial can reach heights of five to eight feet, featuring massive, deeply lobed leaves that can be over a foot wide, giving it a bold, architectural presence. In mid-to-late summer, it is topped with large, airy clusters of small, fragrant white flowers. Uniquely for its family, Glade Mallow is dioecious, meaning individual plants are either male or female; both are needed in proximity for seed production. Native to rich, alluvial floodplains and riverbanks in a limited range of the Midwest, it requires consistently moist to wet soils and thrives in full sun to partial shade. It is a high-value plant for pollinators, attracting a variety of bees, and serves as a host for the rare Bagisara gulnare moth. Because of its size and preference for damp ground, it is an ideal choice for large rain gardens, pond edges, or as a dramatic focal point in a moist meadow.
