![]() Arisaema dracontium (green dragon) |
Arisaema dracontium, the "green dragon," is one of our favorite plants. It appears in moist, shady woods near streams and pools, usually in May. It is a floodplain species, with a growing season that begins after spring floods recede. Green dragon can be found throughout the Midwest, but it is more rare—or almost absent—in northern areas. It has been designated as "threatened" in Québec, and a species of "special concern" in Ontario, primarily because of human development leading to increased flooding in floodplains. The green dragon's composition is very simple: one compound leaf, and one flower stem. The compound leaf is quite large, and divided into 5–13 leaflets that radiate from the curving stem and almost always manage to arrange themselves so that their flat surfaces are parallel to the ground. The flower appears in late May or June and consists of a single, slender "spathe" wrapped in a long "spadix," reminiscent of the flowers of Jack-in-the-pulpit, to which green dragon is closely related. Over the summer the leaves wither away, and the flower is transformed into a cluster of green, then red berries. |
