The plant may also be mulched heavily with fresh straw for harvest whenever the ground is not frozen. Spring harvest is usually completed by late April and early May before the leeks begin second growth and send up a seedstalk. The leek is a member of the onion family, but it is milder than either onions or garlic. The leek has leaves very similar to garlic. They are flat rather than round and hollow like onion leaves.
Elephant garlic is a member of the leek family.
