This grain is widely grown in Ethiopia and Eritrea, and is used to make the bread of the region, Injera . It is a variety of Lovegrass, related to Millet, but with very small grains, averaging about 0.002 inch wide (0.05 mm) and about 0.003 inches long (0.08 mm). Despite this small size, the grains are prolific enough to be worth harvesting. It is grown in both white and brown varieties, with farmers reporting most of their customers prefer the white, but it's the brown that's currently grown in North America.
Domesticated Teff has been harvested in Ethiopia for between 3000 and 6000 years, and is now a minor crop in India and Australia. It is increasingly grown in the western United States as a productive and very nutritious animal forage crop, alternating with alfalfa in the fields. This has made it more available for other uses as well. Ethiopia had a long standing ban on exporting Teff to keep it affordable, but improvement in agricultural practices allowed that ban to be lifted in 2015.
