Oxalis tuberosa.

Oca is considered one of the lost crops of the Incas, is a small starchy tuber from the Andean highlands. Thin skinned, delicately flavored with a texture similar to a baby potato, these appeal to all who enjoy growing and sampling the world’s edible delights. Yields average 2 to 3 pounds per plant. Tubers gain size in late fall so Oca is most suitable in areas free of an early killing frost. Neat bushy plants have attractive clover-like foliage. Leaves have a tangy sour taste and are a good addition to mixed green salads. Mixed varieties, sizes and colors. Unable to ship outside the continental United States
