Oxalis tuberosa


Oxalis tuberosa is actually cultivated on a huge scale in the Andes
and there are dozens of biotypes or cultivars with varying amounts of
oxalates.  The best obviously have little to no oxalic acid .
I've seen colours vary from yellow to red tubers from thimble size
to decent sausages, 
They don't seem to like hot moist summers and rot in the ground
but grow reasonably well in New Zealand and Tasmania.
