Planted what I thought was onions last June and they never got large or looked like onions, so I'm thinking they were shallot plants because they are small clusters of bulbs. They've been in my garden since I planted them, 9 months, and I've only used the green tops like chives. They are nice and green and there are lots of flat bulbs. Can I still use them right out of the ground like onions/shallots? Are they still good? Do they have to be dried first?
