  1. You should plant it leaving only a small amount of the green exposed - outside, in the ground not a pot, if possible. They are fairly easy to grow as is sprouting garlic.

      But...onions are biennial plants. Which means once it has gone through one season and formed a bulb (which yours has) the second season will put it into flowering mode. So if you do plant it, first you'll get some foliage but then it will send up a rather stiff stalk and a not-so-gorgeous flower thingy. The bulb itself will begin to disintegrate. After that, it's game over for the original onion - it's all about the seeds now.
