- Description
-
Cobra Lily is a perennial plant with a tuberous root that is native to Asia and looks tropical. Genus name Arisaema actually is composed of two Greek words aris (referring to the spathe) and aima (referring to some of the species that have red on their leaves).
The species is dioecious meaning individual flowers are either male or female, but only one sex is to be found on any one plant. Therefore, both male and female plants must be grown if seed is required. They are sometimes monoecious and can also change sex from year to year. The plant is pollinated by flies. Tubers should be planted about 10cm deep. Only plant out full-sized tubers and mulch them with organic matter in the winter.
