Elephant Garlic bulbils?

I've got some growing elephant garlic and babbington leek bulbils about 2" high in pots, given by Veggie in the seed swap, thanks V. What do I do with them now? Do they need a nursery bed to mature for a couple of years? Will they produce this year, what conditions do they like, although that question is a bit arbitrary as they'll get what they're given. Help me out here.
