Little Jug

Asarum (ah-SAR-um)

Family: Aristolochiaceae Native Groundcover (<1 ft)

Wild ginger is a genus of 137 species native to temperate areas of Asia, North America and one species in Europe. It is a member of the pipevine family (Aristolochiaceae). The genus name comes from the classical Greek name of a forest plant. These are low-growing evergreen perennials that spread by rhizomes. They prefer moist, well-drained, fertile soil in shady locations. Divide as needed or start from seeds. Wild gingers have pairs of heart-shaped leaves that arise from the underground rhizome and unusual jug-, urn- or bell-shaped brownish to purplish flowers that are often hidden under the foliage in spring. They are pollinated by flies. These plants are not related to ginger, although the rhizomes and leaves smell and taste similar to ginger. It is not recommended to eat these plants due to their nephrotoxic and carcinogenic properties. Use these plants as ground covers in shade, rock, native, winter and woodland gardens. They can also be grown in a container. Insects, Diseases, and Other Plant Problems: No serious problems. Slugs and snails can damage foliage. Rust can sometimes cause issues.
