This group is for those who grow (or wish to grow) Oca (Oxalis tuberosa), a South American tuber which seems to be gaining popularity in Britain and probably elsewhere, too. Since it’s not a widely available or well documented vegetable, the purpose of this group is to bring together the various Folians who are growing Oca this year to share recipes, experiences and growing tips, update the Wiki and maybe facilitate swaps of tubers in time for next year.
