We are thrilled to offer the most incredible elephant ear yet from the breeding program of Hawaii's Dr. John Cho. Colocasia 'Black Coral' represents an amazing breeding breakthrough, forming a 3.5' tall clump of very glossy, jet-black leaves with heavy corrugation. We originally tossed around the name "Exxon Valdez," since it looks like someone covered the leaves in crude oil. We guarantee that visitors will stop in their tracks over this one. Zones: 7b to 10b
