Scientific name

Arisaema triphyllum


Jack-In-The-Pulpit is a perennial wildflower that typically grows about 0.5 m in height. This flower has one or two leaves that grow on opposite sides of the plant from the base. The leaves are large, green colored, glossy, compound with three leaflets, have entire margins, and act like an umbrella over the flower. The flower is unique with the ‘Jack’ being a flower spike and the 'Pulpit' being the outer tube and hood that contains the flower spike. These flowers are showy, light green colored to dark purple with green streaks, and bloom between April and May. Mature hermaphroditic plants produce clusters of bright red berries, which are beneficial to birds and wildlife.
