The rarely offered Arisaema exappendiculatum is an exciting species growing to four feet tall with broad leaflets in a spoke pattern. The spathese are big and thick and bold. They are brown-black or green or a combination of both colours. This will be a stately and exciting addition to the shade garden. Mid-spring. 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.
