Arisaema ringens

This common Asian species is one of the best for gardens. It has glorious three-parted foliage, gray-green and glossy, and a unique green-and purple, rather fist-shaped flower. Arisaema ringens is an easy long-lived garden plant that forms large clumps with time. Worth growing as a handsome foliage plant with the bonus of very cool flowers. Always popular. 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.
