SE Asia (China, Mongolia, Indian subcontinent; grasslands; cultivated thousands of years; garlic-flavored flat leaves; self-seeds prolifically; z3)
Overview
Allium tuberosum is a perennial herb reaching 12-18 inches (30-45 cm) tall with a spread of 12-18 inches (30-45 cm) and an upright, clumping habit spreading by rhizomes and self-seeding. Native to southeastern Asia—China, Mongolia, and the Indian subcontinent—it produces flat, solid, strap-like leaves 0.25 inch (6 mm) wide with a mild garlic flavor (versus the onion flavor of common chives, A. schoenoprasum). Clusters of small, star-shaped, white flowers on stalks above the foliage appear in August-September. Growth rate is moderate to fast. Hardy to zone 3. Both leaves and unopened flower buds are edible. Self-seeds prolifically—can become invasive if flowers are not removed before seed set. Cut-and-come-again harvest throughout the growing season.
Native Range
Allium tuberosum is native to southeastern Asia—China, Mongolia, and the Indian subcontinent—in grasslands and rocky slopes. Widely cultivated across East and Southeast Asia for thousands of years.Suggested Uses
Grown in herb gardens, vegetable gardens, or containers for culinary use—stir-fry, dumplings, egg dishes, garnish. Garlic-flavored flat leaves. Edible flower buds. Perennial z3—returns year after year. Cut-and-come-again. Self-seeds prolifically—remove flowers to contain. Not suitable for areas where self-seeding is problematic.How to Identify

Cut-and-come-again harvest—cut to 2 inches (5 cm) above ground. Remove flowers before seed set to prevent invasive spread.Pruning
Cut leaves to 2 inches (5 cm) above ground for harvest—regrows in 2-3 weeks. Remove flower stalks before seed matures. Divide overcrowded clumps in spring or fall.Container Growing
