Variegated Society Garlic is a terrific perennial plant with narrow, up to 12 inch (30 cm) long leaves. The leaves arise from a rhizome that creeps underground to form clumps up to 24 inches (60 cm) wide. The leaves and flower stems have a garlic odor when crushed. The leaves can be used in salads and in cooking. It is an easy plant to grow whether in the landscape or in containers. They are hardy in USDA zones 7-10.
