A couple of years ago, I'd planted some cloves and totally forgotten about them. They didn't grow much that first season. Anyway, the next year they all sprouted multiple sprouts (unlike the single stem/leaves that usually come up). We kind of assumed that there was more than one clove now, and they were all sending up shoots. We were correct in our assumption.
We dug then after the 2nd season, and had several small cloves in each bunch. Separated them and replanted at the appropriate time. Got small heads from each of them.
Note to self: do not plant garlic in places where they don't thrive, and then forget to harvest. Takes way too long to get a good head of garlic that way
