Last year I tried some shallotts I'd been given by a neighbour who shows them. They didn't do much, but it was a ghastly year, and I've never had any luck with the things anyway. For years, I didn't bother growing them. However, I tried again, in one of my raised beds.
They flourished. I'll be keeping these for planting, to give me a good crop (I hope) next year. It's amazing what a difference a few inches elevation can make. I've long suspected the things failed due to wet soil all winter, and it looks as though I was right.
