Dragon Arum

Arisaema dracontium (air-uh-SEE-muh dra-KON-tee-um)

Family: Araceae Native Herbaceous (3-15 ft)

Green dragon is an herbaceous perennial plant in the arum family (Araceae). It is native to eastern and central Canada and the USA, from Quebec to TX and grows in damp woods. In NC, it is mostly found in the Piedmont but is scattered in the coastal plain and mountains. The species epithet is Latin for “little dragon.” The long exserted spadix bears a fanciful resemblance to a dragon's tail. Green dragon grows in fertile, moist, neutral to acidic woodland soils in partial to full shade. It does not tolerate heavy clay. It will grow 1 to 3 feet tall and 1 to 1.5 feet wide. Propagation is by division or seeds. The plant grows from a corm and sends up a single large compound leaf in spring. The flower that follows is a Jack-in-the-pulpit type bloom, as they are related. This is followed by a cluster of red fruits that the birds enjoy. The plant dies down in late summer. Beware of the similar-looking Pinellia pedatisecta , of China, which is very weedy and aggressive. In Pinellia pedatisecta , the central leaflet of the compound leaf is much larger than the adjacent leaflets. In green dragon, the leaflets are similar in size. Also, the inflorescence of P. pedatisecta rises above the leaves. In green dragon, the inflorescence is mostly below the leaves. Use green dragon in a shady garden, naturalized area, native garden or along streams or ponds. Plant with other shade lovers, such as ferns and hostas, that will fill in the area once the green dragon goes dormant. Please do not disturb plants in the wild, as they are somewhat uncommon. Insects, Diseases, and Other Plant Problems: No significant problems. More information on Arisaema .
