This bulb-shaped veggie is part of the onion family, which also includes chives, leeks, and scallions. Unlike its kin, a garlic bulb is made up of many smaller pieces called cloves. So-called wild garlic is similar, but not the same plant. Neither is elephant garlic, which is really a kind of leek.
Just where and when garlic first appeared is a mystery. Experts believe it was most likely in Central Asia. Records show that people in India and Egypt grew it more than 5,000 years ago.
