Bransford, W.D. and Dolphia

Arisaema triphyllum

Arisaema triphyllum (L.) Schott

Jack In The Pulpit, Indian Jack In The Pulpit, Jack-in-the-pulpit

Araceae (Arum Family)


USDA Symbol: artr

USDA Native Status: L48 (N), CAN (N)

One to two large, glossy leaves, divided into three leaflets, rise on their own stems up to about 2 feet tall. The intriguing blossom of this woodland perennial occurs on a separate stalk at the same height as the leaves. It is a large, cylindrical, hooded flower, green in color with brown stripes. Distinctive "Jack-in-the-Pulpit" formation grows beneath large leaves. A cluster of bright red berries appears in late summer.

Some authorities recognize one species, and others three, based on minor differences in leaves, spathe, and size.
