Bluegrass, Alpine
‘Gruening’ alpine bluegrass (pdf file)
Poa alpina, Cultivar

‘Gruening’ alpine bluegrass was released by the Alaska Plant Materials Center (PMC) in 1986 (Wright, 1991c).  The species is widely adapted throughout Alaska.  As the name implies, the species is adapted to high elevation areas. 

It also performs well on sites drier than those tolerated by Kentucky bluegrass.  Seed availability is limited.  Before this cultivar is included in a planting plan, the availability of the seed should be researched.

Poa glauca, Cultivar

‘Tundra’ glaucous bluegrass was originally collected in Arctic Alaska.  The cultivar was released by the University of Alaska Agricultural Experiment Station for revegetation in extreme northern areas with severe environmental conditions (Mitchell, 1979).

Bluegrass, Kentucky
‘Merion’ Kentucky bluegrass
Poa pratensis, Cultivar

‘Merion’ Kentucky bluegrass was released in 1947 by the USDA Plant Service Research Division, ARS and the U.S. Golf Association Green Section.  The cultivar is more adapted to close mowing than any other Kentucky bluegrass (USDA, 1972).  Merion is often used in lawn mixes in Alaska.

Bluegrass, Kentucky
‘Nugget’ Kentucky bluegrass (pdf file)
Poa pratensis, Cultivar

‘Nugget’ Kentucky bluegrass was released and developed by the University of Alaska Experiment Station in 1966.  The source of this cultivar was a single plant collection made in 1957 at Hope, Alaska.  ‘Nugget’ has outstanding winter survival (USDA, 1972) and is used extensively in Alaska for turf and lawns.

Bluegrass, Kentucky
‘Park’ Kentucky bluegrass
Poa pratensis, Cultivar

‘Park’ Kentucky bluegrass was developed by the Minnesota Agricultural Experiment Station in 1957 (USDA, 1972).  Hardiness of this cultivar is not as good as ‘Nugget’ in extreme northern areas of Alaska.  However, it is still used in volume in Alaska.  Like ‘Nugget’, its use tends to be limited to landscape and lawns.
