Plants which grow well and produce a worthwhile yield, that I like and that have survived at least one winter with temperatures down to minus fifteen degrees centigrade.
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 I simply don’t like. This last is, of course, a matter of personal taste.
A case of my eyes being bigger than my allotment.
