Plant Description

Jack-in-the-Pulpit is a popular perennial wildflower that arises from a bulb-like structure called a corm. Plants have one or two compound leaves with 3 leaflets and grow 18 to (rarely) 30 inches tall. The flowers consist of a green and purple striped spathe (the pulpit) surrounding and arching over a whitish spadix (Jack). It takes 3 years or more for plants to flower from seed. Early summer flowers may be followed by clusters of bright red berries in the fall. Grow this in a rich, moist, shady spot. Plants die back down to the ground right after flowering unless they make berries but should emerge again in mid spring.
