Cush Cush Yam
Dioscorea trifida
Cush cush yam is a tropical climbing vine grown for its starchy tuber, often rated the best-flavored of the true yams when boiled or baked. Reaching harvest takes nine to eleven frost-free months and steady heavy rainfall, conditions no true winter climate can offer outdoors. It carries no known toxicity, allelopathy or spreading habit, so under glass with a long enough warm season it is a low-risk crop to try - the trick is finding it that much time and water, not managing any hazard.
