Arisaema dracontium (L.) Schott
Green Dragon, Dragonroot, Greendragon
Araceae (Arum Family)
Synonym(s): Muricauda dracontium
USDA Symbol: Ardr3
USDA Native Status: L48 (N), CAN (N)
Green Dragon has only 1 leaf; however, the leaf stem forks so that there appear to be 2 separate leaves, each divided into 5-15 unequal leaflets which are arranged palmately (like the upturned palm of oneís hand) on the tip of the forked stem, which is sometimes 20 inches long. A separate flower stalk hold the perennialís unique blossom. 1 greenish, long-tipped spadix (the "dragonís tongue") protruding several inches beyond a narrow green spathe. It is a narrow, greenish, hooded, cylinder with a long, upward-pointing "tongue". There are numerous tiny flowers crowded onto the 6-inch-long flower stem, the lower part of which is enclosed within the leaf stem. The white flowers are very small, with no petals or sepals. Orange-red berries follow.
The long tapered tip of the spadix resembles a large flickering lizard's tongue. (Lamb/Rhynard) Green Dragon is considered relatively rare.
