Green Garlic is what you get when you plant garlic but instead of letting it mature over a long period of time so it can form a bulb you grow it for the green stuff above the soil line. You can use it like an herb. It tastes like garlic except more delicate and less intense. And you can't buy it at the grocery store. So plant it yourself whenever that garlic bulb that has been sitting for a while begins to sprout. Plant it with the pointy or sprouting end up and cover with about and inch of dirt. you can plant the cloves fairly close together since they won't be forming bulbs.
