Seed Garlic: the larger the clove you plant, the larger the garlic bulb you will harvest. Large or medium sizes should be used for planting in order to harvest the largest tastiest bulbs next summer. Cooking Garlic: people who love garlic and most restaurants prefer the ease and convenience of the large or medium garlic bulb. These bulbs have huge cloves that are ideal for cooking or roasting and super easy to peel. Great Taste and Lower Price: those who want gourmet taste in a smaller more economical package find that medium bulbs taste just as good as the larger ones. Some home cooks prefer the daintier clove size. Green Garlic: uses the smallest cloves. Green garlic tastes best when it is small and tender. Green garlic is harvested in the spring before the bulbs fully develops.
