Jack-in-the-Pulpit | Plant Profile

Jack-in-the-Pulpit (Arisaema triphyllum) are small to medium sized woodland wildflowers. The columnar, tube-like single flower gives a tropical appearance to the plant. Three leaves curl over the flower tube to act as sun protection. The roots are poisonous when consumed and may not be pet friendly.

Jack-in-the-Pulpit prefers fertile, medium to wet soil in part shade to full shade. The soil should never be allowed to dry out. A layer of mulch can help to maintain a consistent soil moisture. If grown from seed, expect to wait up to 5 years for a flower to be produced.

Jack-in-the-Pulpit are best left to naturalize in woodland areas or wild flower gardens. Heavy or sun dappled shade is appreciated.

There are rarely serious disease or insect issues that plague this species.
