Bought some Oca (Oxalis tuberosa) to grow this year, anyone with experience
of growing this in the UK?

Also bought Mashua (Tropaeolum tuberosum) to try, both for it's flowers and
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.
