What happens if you plant a store bought onion?

it might flower if the conditions are right.
it may not be suitable for your soil or climate
(they usually like pretty good soil).


Can you cut it into pieces like a potato?

not quite, you need to make sure there is some of the basal
area where roots come out of (this is common among most bulb
species) whereas potatoes will grow from any point on the
potato that has an eye.

commonly it's just not worth it because the onions often
have so many seeds from flowers that will grow that it's a
waste of something edible to do that.
