Plant Description

Japanese Cobra Lily is a very elegant cousin of our Jack in the Pulpit. The flower is composed of a pure white spadix or Jack that looks like a big puffy marshmellow surrounded by a pitcher that is glowing white inside and dark purple/black on the outside with a dark striped hood. Single flower stalks come up in mid-spring with a pair of 5-lobed glossy green leaves reaching about 12 to 20 inches tall. Unlike many other Arisaemas, the foliage stays up all summer. 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.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.
