ARISAEMA ringens

Plant Common Name

Cobra Lily

General Description

Arisaema ringens, the Japanese cobra lily, is a tuberous herbaceous perennial native to East Asia. In early spring two large glossy trifoliate leaves emerge, overtopping a cobra-like "flower" that comprises a pale green, purple- or white-striped, hood-like spathe and a club-shaped spadix. A purple-mottled sheath surrounds each leaf stem. Bright orange berries ornament the spadix in late summer and fall.

Japanese Cobra Lily grows best in partial shade and moist, humus-rich soil. Its emerging leaves are vulnerable to late frost. It makes an excellent addition to a shade garden.
