Berseem clover, Trifolium Alexandrinum, is a cool-season annual legume that is native to the Mediterranean region. For millennia, it has been the foundation for agriculture in the Nile Delta, featuring salt tolerance, high nitrogen fixation, and a synergistic relationship to alfalfa. Frosty, while preserving its Mediterranean genetics, has been bred for later maturity, cold tolerance, productivity, and nutritional value.
