Apparently Purple Yam, Winged Yam etc. (D. Alata) is grown as a staple crop in many parts of the world. From what I've read, it can be grown as an annual in USDA Zones 6-10. I'm in Zone 6, and I was looking for any information about growing these in more temperate climates, (Like what kind of yield I should expect-will it be very small because of the shorter warm season than the tropics?). Does anyone have any experience with this? Any information will be helpful.
