    Cobra Lilies Overview

    Arisaema is a genus containing around 197 tuberous perennials from the Araceae family. These plants produce large flowers consisting of a tall hooded spathe around a pencil-shaped spadix. This spadix is edible and has been consumed historically in times of famine. They are known by names such as Cobra Lilies and Jack-in-the-Pulpit in different locations due to their distinctive flower. They originate from Asia, Africa and North America and Mexico, with most species found in Japan and China. They are grown mainly for their interesting flowers and attractive foliage.
