The following are recommended Kentucky Bluegrass varieties from the Virgina and Maryland turfgrass variety trials. Kentucky bluegrass best used as a mixture with turf-type tall fescues and not as a stand alone lawn in southern Delaware. In northern Delaware, they can be used more extensively.
Kentucky Bluegrass – Individual varieties selected must make up not less than 10%, nor more than 35% of the total mixture on a weight basis. All varieties must be certified. Selections can be made from Category I alone or various combinations of Categories I, II, and III as noted. Kentucky bluegrasses listed as “Promising” (Category III below) can account for no more than 35% of the blend by weight).
Category I – Recommended Kentucky Bluegrass Varieties (65–100% of blend by weight).
Apollo, Award, Awesome, Beyond, Blackstone(1), Bordeaux, Brilliant, Cabernet, Champlain, Courtyard, Dynamo, Everest, Everglade, Excursion, Glenmont, Impact, Liberator, Limousine, Midnight, Moonlight, NuDestiny, NuGlade, Perfection, Princeton 105, Quantum Leap, Rambo, Raven, Skye, Total Eclipse, and Tsunami.
Category II – Special use varieties (10–35% on a weight basis) – These varieties have been noted for specific enhancement of Kentucky bluegrass performance as related to shade tolerance and reduced maintenance requirements.
Shade Tolerant: Ascot, Brilliant, Liberator, Moonlight, NuGlade, Princeton 105, and Quantum Leap.
Low Maintenance Tolerant: Baron, and Midnight.
Category III – Promising Kentucky Bluegrasses (10–35% on a weight basis) – These grasses have performed in the top statistical quality category for a minimum of 2 consecutive years in Virginia and Maryland trials. Seed may be difficult to locate for some cultivars. Note: Durablue, ThermalBlue, and ThermalBlue Blaze are commonly referred to as Hybrid Bluegrasses, but they are classified by USDA as Kentucky bluegrasses. To date they have had better performance in traditionally warmer areas of Virginia.
