Cool season, moderately drought tolerant, long-lived sod-former. Vigorous rhizomes adapted to deep soils. Productive, starting growth in early spring, ripening by early summer and producing abundant late summer and fall regrowth. Highly palatable to livestock when green, fair palatability to wildlife.

Days to Germination:


Carlton - Leafy, high yielding forage variety used for hay and pasture. Candidate for mine reclamation having demonstrated a tolerance to industrial soils. Considered to be best suited to the northern U.S. and Canada. High seed yields. (Released 1961, origin: Saskatchewan, CAN)

Lincoln - Aggressive, develops strong rhizomes and forms sod. Easy establishing with good seedling vigor. Considered to be best suited to the southern half of the U.S. (Released 1942, origin: CA, originally from Hungary)

Manchar - Mild sod-former which does not become sod-bound as quickly as Lincoln. Maintains good balance with legumes. Used throughout the west and northern latitudes of the U.S. (Released 1943, origin: Manchuria, China)
