Nursery contributed plant descriptions

Arisaema dracontium is the rare second species of jack-in-the-pulpit native to eastern North America. Its better known relative is A. triphyllum. However, these two species are not closely related, each having closer kin in Asia. A. dracontium is a member of section Tortuosum and resembles A. tortuosum with a tall green stem to three feet holding 7-13 leaflets. The inflorescence is usually held below the leaf. The spathe is green and gives rise to a dramatic, curling, green to yellow to orange, tongue-like spadix appendage in mid season. Orange-red fruit follows in summer and fall. Needs rich well-drained soil in shade. Occurs in southern Ontario south into the US. Arisaema are known as cobra lilies or jack-in-the-pulpits. There are only two North American species but many in Asia. They grow in moist, shaded, forested habitats and are great for adding cool foliage and floral intrigue in the shade or woodland garden where they can rise up and through other shade plants. In colder climates they can be grown in pots and protected in winter. Keep just above freezing. In pots, plant in a moist but free-draining mix of coarse bark and pumice or perlite. Pull back on watering when dormant.
Our native "Green Dragon" can get quite tall if given the moist, rich soil and shade that it loves. It's very easy to grow and puts out a very large spathe with a single five bladed leaf. A mature plant can grow up to 4 feet tall under favorable conditions.
Blooms: spring-summer, green, long spadex/ green fingered foliage Zone 5-9. 3', Eastern US, part shade-shade, moist, well drained.
