Try Oca, a Terrific Tuber 

Originating in the Andes and long a staple food throughout South America, this member of the oxalis family produces foliage similar in appearance to wood sorrel and underground, sunchoke-like tubers. Known by many names (Uqa, New Zealand Yam, Trufette Acide, to name a few), Oca comes in many shades, from cream to orange and red to purple.

Now available from our friends at Mustard Seed Farm, this rosy-hued variety is a stunner.
