In Southeast Asia, and all the way to Hawaii, the winged yam Dioscorea alata, known variously as ube, ubi, or uhi, depending on location, is an important root crop. It's notable for this strong purple color, which confuse a lot of folks into thinking that it's artificially created. Note that this is not to be confused with the Okinawan purple sweet potato - which is an Ipomea.
