What happens if you let an onion grow?
The outside will become dry and papery, and the whole onion will shrink as it puts stored energy into trying to make one last go at life. Once an onion has sprouted, there’s nothing wrong with eating it. Provided it’s not actually spoiling or molding, it’s still fine to cut up for dinner.

What happens if you leave an onion in the ground?
If you leave a mature onion in the ground over the winter instead of harvesting it as recommended, the mature onion will begin to multiply. The onion that is left in the ground will begin to form sections, much like a garlic clove. Those sections can then be separated and planted as sets each spring.
Do onions grow from seeds or bulbs?
In the first season, onions will grow from a seed to a plant and then a dormant bulb. After a period of cold temperatures, onion bulbs will grow and flower in the second season.
