Allium thunbergii, English common name Thunberg's chive,^[2] is an East Asian species of wild onion native to Japan (incl Bonin + Ryukyu Islands), Korea, and China (incl. Taiwan).^[3] It grows at elevations up to 3000 m. The Flora of China recognizes A. tunbergii and A. stenodon as separate species, but more recent sources combine the two.^{[1][4][5][6][7][8]}

Allium thunbergii produces one or two egg-shaped bulbs up to 20 mm in diameter. Scapes are up to 50 cm tall. Leaves are longer than the scape, hollow, triangular in cross-section. Umbels are crowded with many red or purple flowers.^{[4][5][9][10][11][12][13]}
