Jack-in-the-Pulpit (Arisaema triphyllum) is a spring ephemeral plant with green blooms from mid-to late spring. They prefer moist to mesic soil in part sun or shade. They are best suited for slopes where they’ll grow up to 2 feet tall. They should be interplanted with species that fill in the voids left once dormant in summer. Companion plants include Rosy Sedge (Carex rosea) and Woodland Phlox (Phlox divaricata).
Jack-in-the-Pulpit is attractive to slugs. If foliage damage is occurring during the growing season, hand-pick the slugs from the plant. Nearby plants should be designed to fill in the gaps left behind when the plant goes dormant in the summer.
