Bush Morning Glory-Sweet Potato Relative
This perennial species of morning glory is found in the western U.S.as far north as South Dakota. Young roots said to have a flavor similar to sweet potato. Its name is derived from the size of its taproot which can be 2 ft. across and 5 ft. long weighing up to 25 lbs. Obviously drought and meteorite tolerant. Not much is known about cultivating it for its edible roots, but the consensus is the small roots when 2-3 years old have the best flavor and are said to be sweet and tender. Possibly it can be cultivated from root cuttings too. Needs a sunny dry location.
