Plant Description

Cobra Lily is a very cool, exotic looking cousin of our Jack in the Pulpit. From a large horseshoe shaped leaf with 11 to 17 leaflets, a single flower (Jack) emerges on a glaucous, dusty, blue/purple stem. The outside of the Jack is light beige with purple and brown spots while the inside is dark purple/brown. Jack himself, the spadix, is dark purple and ends up with a long snaky, whip-like tail sometimes reaching 18" in length. Very exotic looking! The hood or spathe is also dark purple/brown. Successful pollination (requires at least 2 plants) may result in bright red fruits in late summer. Otherwise, Cobra Lily will go completely dormant by mid-summer. Give this one shade and average to good soil but NO excessive winter moisture which will cause it to rot away in a second. It is very common in the trade in Japan because it is easy to grow and because of its very attractive leaves.

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.
