Allium ochotense
Also called Myeongi, Far Eastern Broad Leaf Allium
Allium ochotense is a wild onion species from East Asia and the Russian Far East, grown in cool temperate climates for its strongly garlic-scented leaves and bulbs. It is a slow-growing bulb that takes about four years from seed to harvest, so it suits patient gardeners in cold regions.
Allium ochotense, or the Siberian onion, is a primarily East Asian species of wild onion native to northern Japan, Korea, China, and the Russian Far East, as well as Attu Island in Alaska.
Some authors have considered A. ochotense as belonging to the same species as A. victorialis, but more recent authorities have treated it as a distinct species.
From around 1990, it has been grown horticulturally in Hokkaido and snowy regions on the eastern side of Honshū. Outbreaks of plant disease have been reported in these onion paddy farms. It requires approximately four years from sowing to harvest.
Researchers have identified 1-propenyl disulfides and vinyldithiins as odor compounds. Specific odor agents include: "methyl allyl disulfide (Chinese chive odor), diallyl disulfide (garlic-like odor), and dimethyl disulfide and methyl allyl trisulfide (pickles-like odor)".
Allium ochotense is centered in the Amur River basin area, thus, it occurs in the Amur, Khabarovsk, Primorye regions of Siberia, and into Sakhalin and Kuril Islands within the Russian Far East. In China, the plant grows in Inner Mongolia and China (Heilongjiang, Jilin, Liaoning), Hebei, Henan, Anhui, Hubei, Zhejiang, Shaanxi, Shanxi, Gansu, and Sichuan). The range also includes Korea, in Ulleungdo and the high mountains (over 1,000 metres (3,300 ft)) in the Korean Peninsula, including Paektu Mountain, and Japan (Hokkaido and Honshu), in colonies from Hokkaido down to the Kinki area (Nara Prefecture), in coniferous and mixed forested wetlands in subalpine terrain. The plant's range extends nominally into the United States, but A. ochotense is only found natively growing on Attu Island, the westernmost island of the Aleutian archipelago. There are colonies on Unalaska Island, but they are thought to be introduced.
