The Story

Plant Bio

Arisaema dracontium, or Green Dragon, is a unique woodland perennial featuring a single, deeply divided leaf and a distinctive flower (spathe and spadix). The flower consists of a greenish spathe (hood) from which a long, slender, tongue-like spadix protrudes. The most striking feature is the long, green to yellowish 'dragon's tongue' (spadix) that extends well beyond the spathe. In late summer, it produces a dense cluster of bright red-orange berries.
