Can I grow garlic from seed?

Yes you can plant them though it is more usual to plant individual garlic cloves. November is a good time to plant garlic.

garlic is actually a perennial but its normally cultivated the next year from cloves planted in the autumn. If you grow from the seeds on a flower head it will be 2-3 years before you can harvest the garlic - it will come up next year but you'll need to leave it to come back up again for a couple more before the bulbs are reasonable size.

Sound like bulbils were produced (familiar with Leeks doing this in their flower heads and the ornamental, Allium giganteum too) so should be fine to propagate using them. Maybe have a year in advance on the seed then but still take at least one more year than a clove.
