It is cultivated widely throughout the world, ranging from Siberia to tropical Asia, including China, Japan, Korea, Taiwan, and the SE Asian countries.

It has been grown for centuries in China, Japan, and SE Asia . This hybrid has characters from both parents. It develops a distinct bulb like the shallot, and terete leaves like A. fistulosum but slender and very erect. The flowers are subcampanulate as in A. cepa, but the stamens exceed the perianth and the inner filaments are without lateral teeth at the base as in the other parent The hybrid is completely sterile and does not form fertile seeds.
