Allium tuberosum is a perennial plant[7] growing from a small, elongated bulb (about 10 mm, 13⁄32 inch, across), tough and fibrous, originating from a stout rhizome.<ref name="des"/> It has a distinctive growth habit with strap-shaped leaves 1.5 to 8 mm (1⁄16 to 5⁄16 in) wide[9] unlike either onion or garlic. It produces many white flowers in a round cluster (umbel) on stalks 25 to 60 cm (10 to 24 in) tall.[5] 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]
