Cultivation

An unusual plant with 1-4' tall stems supporting a single leaf that resembles dragon wings when emerging alongside the flower spike in spring. Inflorescence consists of a narrow, tapering sheath (spathe) and long tongue of many tiny flowers (spadix).
Light: part to full shade.
Moisture and Soil: moist, rich soil - likes flood plain forests and riverbank meadows.

Propagation

Seed Treatment and Storage: Remove red pulp and keep seeds moist after harvesting. Cold moist stratify
for 60-90 days (warm moist then cold moist). The young plant will send up one leaf the second spring.

Biocultural value

The Menominee used green dragon medicinally for gynecological disorders and included the root in sacred bundles, where it was said to give the power of supernatural dreams to the owner.

Wildlife value

Green dragon flowers attract simple flies (suborder Nematocera), who pollinate the tiny, aggregated flowers. Woodland birds such as the wild turkey and wood thrush eat the fruit. Mammalian herbivores avoid the toxic foliage.

Poisonous

yes

Poisonous description

The entire green dragon plant contains needle-like crystals of calcium oxalate which become embedded in mucus membranes if ingested and cause intense pain and a burning sensation. Calcium oxalate is particularly abundant in the rhizome. Those who eat it rarely go beyond the first taste. Most of the plants in the Araceae (arum family) have this property.
