Rugby II Kentucky Bluegrass
Thatch resistant
Moderately aggressive
Good shade/sun tolerance
Shiny dark green color
Low maintenance
Description
Rugby II originated from a plant selection from a 1930’s cemetery in Washington State. The original plant had spread to a diameter of 20-30 feet across, growing in a low maintenance cemetery in an arid environment. When found, the spot was dark green, shiny and dense, in spite of growing between a huge shade tree and a well traveled driveway.
Rugby II scored among the top 14 entries in a recent NTEP Kentucky bluegrass trial under medium-high maintenance. It ranked in the top 10 in Indiana, Illinois, Washington state, Missouri, Rhode Island and Alberta, Canada.
Rugby II showed strong quality performance at a cutting height of ½ inch. It was the #1 entry out of 3000 experimental varieties in a recent close cutting trial in Post Falls, ID. It was immune to several Poa Annua control chemicals commonly used for fairway maintenance.
