Collecting and Growing Jack-in-the-Pulpit from Seed

Jack-in-the-pulpit (Arisaema triphyllum) produces red berries in fall. Wear gloves—seeds can cause skin irritation. Remove pulp, plant seeds ½ inch deep in a moist, shady bed. Seedlings appear in mid-summer. Keep moist, grow one season, then transplant to permanent woodland site next spring.

They naturalize well in rich, damp shade. Patience is key—flowering takes a few years.
