(syn: Sida dioica) Here is a very cool plant to fool your favorite know-it-all gardener. This North American native perennial (from Minnesota south to Virginia) is found in moist prairies, ditches, and marginal wetlands. Napaea dioica is a hibiscus relative that will make even the most avid gardener swear it's a ligularia. The 11-lobed, dark green leaves form a 3' wide basal clump that looks quite saxifragesque. In early summer, Napaea dioica stalks rise to 7' tall, topped with clusters of white malva-like flowers. We have found napaea to grow best in a moist, partial-sun site.
