Bought some Oca (Oxalis tuberosa) to grow this year, anyone with

the edible tubers (not that I might eat many considering their
reputation!)

What reputation?

I have grown both. Oca straggles badly, but the tubers don't really
start growing until the days shorten, so they don't get very large with
me. It is a very pleasant, slightly acidic, potato-like object.

I didn't eat the latter, because I didn't know it was edible at the
time, but it grows well and is quite pretty.

The tubers of both are very sensitive to frost.


Thanks Nick, we will see how Oca does on our heavy acidic soil and
neither of us has eaten it so it will be interesting. As for Mashua, it
has the reputation of having the same effect as Bromide in the tea. :-)
or should that be :-( .

You might find it easier to grow Oca in large pots, it's easier to find
the tubers
