I've started leaving onions in the ground over winter. Not sure where you are located, but it seems to work here in Wisconsin. They grow a little more the next spring, and they've seeded so I get MORE little ones that i can transplant.

 

Both are doing what is normal for them. Regular onion varieties are a hardy biennial, even in very cold zones. They grow for a certain period and then go dormant. When they resume growing, their immediate action is to produce seeds. When that is fulfilled, they die. Your onions are now in that second stage and will supply you with green onions for awhile. Garlic is equally hardy and is regularly planted in the fall. If there is fall growth, it is suspended during the winter and resumes again in the spring.

Eat'm! I purposly plant a wide row of onion bulbs just for this purpose. (See thread in Countryside Families). My row is about 30 - 35 feet long and the width of a garden rake. I plant hundreds of onion bulbs all down this row and I eat off of them 3 times of the year. Late spring, fall, and early spring the next year. I'm eating green onions in Febuary/March while everyone else is wishing. I've already had two onion omlets meals for breakfast in the last few days.
