Cold detector Mk ll

My Oca crop took over the rest of the crops; lesson learnt if there's a next year.
There could well be - planted as early as should be, rather than when was.  They're supposed to have a yellow flower somewhat akin to wood Sorrel.  Harvested after "the first frosts when the foliage will die back."  To date the Shed end hasn't dipped below +3˚C; seems the Oca hasn't either.
