Garlic chives (Allium tuberosum) grow more quickly than regular chives and have a delicious, mild garlic-onion flavor. The flowers are borne in pleasing clusters on stalks up to 30 inches tall, much taller than the leaves. A perennial, its clumps can be divided and it also reseeds prolifically. Tip: The flowers can be a lovely addition to bouquets and floral arrangements.
