As I said, I have thrown some away, the really weedy ones.
They do come up every year but I am not sure if they are truly hardy everywhere. My daughter keeps hers but she is in Cornwall, much warmer.
Maybe keep some back, the best ones ,pot up and keep in the greenhouse if you can, they may be better next year, as most things are.
