The plant name, translated, means: Arisaema: Greek aris, a kind of arum, and haema for "blood" - dracontium: Latin for "of the dragons" probably for the deeply divided leaves resembling a dragon's claw.

A beautiful, usually small, native plant, that grows in rich, often wet woodlands, Zones 8-9b. Requires moist soil, high in organic matter, and prefers a sheltered location, especially from wind, with dappled light in the spring, and shade in the summer. Has "dazzling, bright red berries" in the fall. This info is from "A Gardner's Guide to Florida's Native Plants," by Rufino Osorio, published by the University Press of Florida in Gainesville.

Very similar to Jack-in-the pulpit, except green dragon usually has only one large, long-petioled, compound leaf that is divided into 7-15 lance-shaped leaflets and has a greenish spadix which is narrower and tapers up and beyond the less prominent, greenish hood (lacks the distinctive purple striping of Jack) of the spathe. Also like Jack-in-the-Pulpit, this plant goes dormant in the summer, with the mature plants producing red berries which become visible in mid to late summer as the spadix withers. Roots contain calcium oxalate (same chemical as in Diffenbachia or dumb cane) and are poisonous in an uncooked state.
