The Aroid Family: Genus Arisaema

The Araceae is the family of aroid and related plants. Members of the Superorder Aranae, the aroids are mostly rhizomatous plants, although some have a corm or tuber. (Discussion based on V.H. Heywood, "Flowering Plants of the World" Mayflower Books, New York, 1978.)

Arisaema sikokianum The genus Arisaema contains the "Jack in the Pulpits" found around the world in the Northern Hemisphere. This example, Arisaema sikokianum, is native to Japan.

Arisaema ringens Arisaema ringens is another Asiatic species that blooms early in the season and is hardy in USDA zone 5. It grows in shade or partial shade.

There seems to be one major pest that afflicts Arisaema, the Arisaema Rust, Uromyces ari-triphylli. The currently recommended treatment for Arisaema Rust is total destruction of all the afflicted plants in a collection, according to some in the Arisaema Enthusiasts Group.

There are some terrific Arisaema and Aroid sites on the Web:
