Arisaema triphyllum

Outstanding Qualities

Commonly known as Jack-in-the-pulpit, this eastern wildflower is an unusual addition to the shade garden. In mid-spring the foliage bursts from the ground topped with odd looking hooded flowers. The bloom color can vary from lime green with mint green stripes to dark brown with chalky white stripes. As the flowers mature the trillium-like leaves open above and hide them from view. The flowers will set a large seed head that will ripen to a bright red-orange in early fall.

Culture Notes
Arisaemas grow best in a rich well-drained soil, preferring a sandy loose soil. Choose a location with light to open or dappled shade and avoid hot afternoon sun. Do not bury the tuber too deep, it will grow best when the top is covered by an inch or less of loose sandy soil and compost. Water these plants regularly in the summer. Arisaema can be very slow to sprout in the spring, sometimes they may not start growing until early to mid-summer. Be patient especially with newly planted tubers.
