Japanese Cobra Lily is a very elegant cousin of Jack-in-the-Pulpit. The flower is composed of a thick purple and white striped spathe that curls down, resembling a cobra's head. The spadix, or Jack, is dark purple. Single flower stalks come up in mid-spring below a pair of giant, 3-lobed, glossy and thick green leaves reaching about 12 inches tall. Unlike many other Arisaemas, the foliage stays up all summer. Although it is very easy to grow, excessive winter moisture is death to these plants. In time, they may form large clumps.

The spathe is usually green and white or purple/brown and white striped with a purple/brown lip. Pseudo-stem, petioles and peduncle vary from green to a dark purple/brown. A once common but now difficult to find form with a green lip and green and white spathe also exists. This form usually has a green pseudo-stem, petioles and peduncle.
This one will produce offsets unlike some of its cousins. Native to Japan, Korea and China.
