BenefitUse Food: EDIBLE PARTS: Leaves, bulbs and bulblets. Field garlic (A. vineale) is too strong for most tastes. Gather leaves during spring and fall. Gather bulbs in the second year when they are large enough to use like cultivated onions. Flower stem bulblets are collected during the summer. Use as domestic onions, for seasoning or raw in salads. Bulbs can be used raw, boiled, pickled or for seasoning. Their strong taste can be reduced by parboiling and discarding the water. To freeze onions or garlic, one should coarsely chop, blanch two minutes, drain, pat dry and place them into plastic bags. The bulbs can also be dried for use as seasoning. Use flower bulbs to flavor soup or for pickling. (Poisonous Plants of N.C.)
