Arisaema serratum
Japanese Cobra Lily Zones: 5, 6, 7, 8, 9
This Cobra Lily is a tall and vigorous cousin of our Jack in the Pulpit. Its native habitat is in moist, cool forests in Japan. The flower is composed of a black spadix or Jack surrounded by a pitcher that is dark purple/black on the outside and white and black striped on the inside. Single flower stalks come up in early spring with a pair of 5-lobed mottled green leaves reaching about 3 to 4 feet tall. A mature plant is very impressive. If you are lucky and the flowers were pollinated (you need at least 2 plants), you may see bright red berried fruits in late summer.

Japanese Cobra Lily wants partial to full shade and moderate to moist soil during the growing season. Excessive winter moisture is death to these plants. So be sure they are in a site that is well-drained!

It is truly a gem for the shaded garden. These plants may come potted or bare root depending on their stage of growth but they are of blooming age. They are shipped only when NOT actively growing. Generally this means no shipping between April first and August.

- Just bought one. It is huge and gorgeous. I cannot wait to see what it does. Right now it looks like a thick speckled pointed stick coming up from the ground.
