Cold Hardiness of Forage Grasses Grown on the Canadian Prairies

Cold hardiness ratings of 18 forage grass species, and cold hardy reference cultivars of winter wheat (Triticum aestivum L. ’Norstar’) and rye (Secale cereale L. ’Puma’), were compared to provide estimates of the winterkill risk for forage grasses established in the spring and fall on the Canadian prairies.
