Perennial.
Garlic chives are also known as Chinese chives, Chinese leek, Ku chai, Oriental garlic chives or, in Japanese, Nira.
The plant has a distinctive growth habit with strap-shaped leaves unlike either onion or garlic, and straight thin white-flowering stalks that are much taller than the leaves. It grows in slowly expanding perennial clumps, but also readily sprouts from seed. Besides its use as vegetable, it also has attractive flowers.
