I dug up a couple of my elephant garlic today (baseball-sized, thank
you very much) and discovered three or four tiny, hard nodules
attached to each.

These nodules are yellower than the rest of the bulb, they are
super-hard, but they smell and taste like garlic ought to.

They look like tiny individual garlic cloves, but they aren't
interspersed with the rest of the cloves; they are more or less
simply attached to the outside of the bulb proper.

What the hell are these things? Can I plant them?
