Narrative

Characterized by outstanding winterhardiness, abundant rhizome population, very dense, dark green turf with vertically oriented leaves, tolerance to close mowing, high tolerance to natural infestations of powdery mildew and Helminthosporium at Palmer, and rapid germination and vigorous seedling development. Semi-dwarf. Seed yields over 1000 kilograms per hectare. Susceptibility to snowmold in Alaska comparable to that of other cvs. Used primarily for turf and is the only known cv. of Kentucky bluegrass sufficiently winter-hardy for reliable use in Alaska.
