Tried and tested
Plants which grow well and produce a worthwhile yield, that I like and that have survived at least a couple of winters in my allotment or nearby with no special protection.
Still on parole
Plants which I have in the garden and which show promise, but which I haven’t tried eating yet, which haven’t survived a winter yet or which I’m just generally not sure of.
Plants which haven’t done well in the climate here, that have behaved badly, that don’t produce a worthwhile yield, that are far too fiddly to harvest or that taste really bad. While this last is a matter of taste, I’ve tried to only include a plant for this reason when others I have spoken to generally seem to agree.
A case of my eyes being bigger than my allotment.
