|Eddoe or Eddo is a tropical vegetable often considered identifiable as the species Colocasia antiquorum, closely related to taro (dasheen, Colocasia esculenta), which is primarily used for its thickened stems (corms). It has smaller corms than taro, and in all but the best cultivars there is an acrid taste that requires careful cooking.
Eddoes appear to have been developed as a crop in China and Japan and introduced from there to the West Indies where they are sometimes called “Chinese eddoes”. They grow best in rich loam soil with good drainage, but they can be grown in poorer soil, in drier climates, and in cooler temperatures than taro. (Source: Wikipedia)
