Eddoe

Eddoe or eddo is a species in genus Colocasia, a tropical vegetable, closely related to taro (dasheen, Colocasia esculenta), which is primarily used for its thickened stems (corms). In most cultivars there is an acrid taste that requires careful cooking. The young leaves can also be cooked and eaten, but (unlike taro) they have a somewhat acrid taste. Linnaeus originally described two species which are now known as Colocasia esculenta and Colocasia antiquorum of the cultivated plants that are known by many names including eddoes, dasheen, taro, but many later botanists consider them all to be members of a single, very variable species, the correct name for which is Colocasia esculenta.
