Here's how it works:
Year one: Plant the hard brown pips that are attached to the mother garlic in late September/early October. It will sprout green leaves that look remarkably like leeks. Wait about 10 months. It will not flower and you, dear gardener will leave it in the ground.
Year two: Wait some more. It will sprout again and grow all winter but...this spring it will send up a flower shoot which you, gentle gardener, as soon as you notice, will pinch off as soon as you notice. This will allow your Elephant garlic to get bigger. Wait for the leaves to turn brown, pull it from the ground and you will have a milder version of the garlic we all know and love.
