Spelt

Spelt found great favor in Hungary, much of Eastern Europe and Germany, and in the agricultural Alpine regions for many centuries, but soft winter habit spelt was supplanted by hard red winter wheat when roller milling for refined flour became widespread after 1880. The advantageous characteristics of spelt include winter hardiness, disease resistance, and toughness of chaff that discourages attack by birds and insects. Spelt also is unlikely to sprout during a rainy summer when it nears maturity. Spelt wheat is not free threshing. Source: The Whole Grain Connection
