Nursery contributed plant descriptions

Arisaema tosaense is a tall, vigorous cobra lily from Shikoku Island, Japan. The green (sometimes burgundy) spathe has a long-extended tip and droops way down over the face of the tube. The translucent spathe is especially beautiful when back-lit. Easy garden plant. Late spring bloom. 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.
