Allium tuberosum

Allium tuberosum (garlic chives, Oriental garlic, Asian chives, Chinese chives, Chinese leek) is a species of plant native to the Chinese province of Shanxi, and cultivated and naturalized elsewhere in Asia and around the world.[1][4][5][6]

Allium tuberosum is a rhizomatous, clump-forming perennial plant growing from a small, elongated bulb (about 10 mm, 13⁄32 inch, across) that is tough and fibrous.[7][6][8] Unlike either onion or garlic, it has strap-shaped leaves with triangular bases, about 1.5 to 8 mm (1⁄16 to 5⁄16 in) wide. [9] It produces many white flowers in a round cluster (umbel) on stalks 25 to 60 cm (10 to 24 in) tall.[4] It grows in slowly expanding perennial clumps, but also readily sprouts from seed. In warmer areas (USDA zone 8 and warmer), garlic chives may remain green all year round. In cold areas (USDA zones 7 to 4b), leaves and stalks completely die back to the ground, and resprout from roots or rhizomes in the spring.[10]

The flavor is more like garlic than chives.[9]
