I found an easy-to-use Directory at the Whole Grains Council. In Arizona, Hayden Mills works with several small grain farmers which grow Heritage Durum Semolina. Ramona Farms offers Sonora Wheat, Pima Club Wheat, and Corn. BKW Farms has Sonora Wheat and Khorasan Wheat. There was a history of growing Emmer, Red Fife, Black Nile and Tibetan Purple barley, Yellow Corn, Chickpeas, Hard Red Spring that I am seeing not being grown commercially.
