Seriously though... It's one of the alliums that displays all four methods of reproduction, though getting it to flower as a flower can be hard.... normally it forms multiple split corms at the base, hardneck varieties generally produce a stem with a multiplying onion-style group of bulbils on it, however under some conditions this structure will also contain flower parts as well or instead. You will also find occasionally that offset corms are produced (hardened bulbil structures outwith the usual corm sheath....
I might have nomenclature wrong there but it describes the lot.... real garlic flowers are rare, if you get one I'd always try to harvest the seed and see what you get, it's a new strain....
