Its name comes from the flower’s structure, which looks like a preacher standing inside a pulpit: the hooded spathe covers the central spadix.

Jack-in-the-Pulpit is sequentially hermaphroditic—it can change sex from male to female depending on its energy reserves. Small plants are usually male; larger, older plants become female.

After flowering, female plants produce clusters of bright red berries in late summer to fall, adding ornamental interest.

Raw parts contain calcium oxalate crystals that can burn the mouth, but indigenous people used careful drying or cooking to make it safe for food and medicine.

Can live decades in the same spot, thriving in rich, moist forest soils.

he plant attracts fungus gnats and other small insects with its scent, which mimics decaying organic matter.
