jack-in-the-pulpit (sh) and tuberous (medicine)


jack-in-the-pulpit (sh)




North American plant (Arisaema triphyllum) of the arum family, noted for the unusual shape of its flower.

One of the best-known perennial wildflowers of late spring in the eastern U.S. and Canada, it grows in wet woodlands and thickets from Nova Scotia to Minnesota and south to Florida and Texas. Three-part leaves on each of two long stalks overshadow the flower, which consists of a conspicuous green-and purple-striped structure called a spathe ("pulpit") that rises on a separate stalk. The spathe curves in a hood over a club-shaped spadix ("jack") that, at its base, bears minute flowers. In late summer the plant produces a cluster of brilliant red berries that are poisonous to humans but are eaten by many wild animals.
