Supreme lawn grass seed is an extremely high quality Kentucky blue-grass seed type that is ideal for Colorado lawns and used by grass seeding companies for lawns with little shade. It is a fine bladed type of grass, with deep dark green color, excellent tolerance to foot traffic, fair heat and drought tolerance, good winter hardiness and is disease and fungus resistant. Bluegrass’ one drawback is its poor ability to establish in heavily shaded areas. Bluegrass needs about 70% sunlight throughout the day to stay healthy in a Boulder or Fort Collins area lawn. If a homeowner has tried numerous times to seed an area of the lawn with little success, chances are there isn’t enough sunlight for the bluegrass sod or grass to sustain in that area. Emerald III grass seed would be the best option for an area that does not receive as much sunlight.


Bluegrass is the most common grass type in Colorado lawns used by many grass seeding companies. This is due to the fact that bluegrass is easy to sod and they are virtually drought proof. Even though they require more water to stay green than fescue lawns, if a bluegrass lawn receives zero water, the bluegrass lawns will go dormant and this makes a bluegrass lawn virtually drought proof. When water becomes available again (even if it is one year later) a bluegrass lawn will come out of dormancy. Bluegrass is virtually drought proof.


Bluegrass Facts:

  • Bluegrass grass seeds take 23 days to germinate from seed.
  • Due to strong rhizomes (roots that grow underground and then produce another blade of grass) bluegrass is very good at filling in bare areas and are more durable to foot traffic. Therefore, bluegrass is a good selection for sports turf, lawns with heavy dog traffic or lawns where children play.
  • Bluegrass lawns requires more water to stay green than fescue lawns, but bluegrass lawns will not die if it goes into a severe drought. Bluegrass lawns will go dormant and turn brown quickly if water is reduced. Therefore, bluegrass lawns are are drought proof, but fescue lawns are more drought tolerant.
  • Bluegrass will not grow very well in full shade. Bluegrass lawns needs 70% sun per day to stay healthy.
  • There are over 100 different cultivars of bluegrass. The bluegrass in supreme seed mix is selected for its high tolerance to heat and drought stress and its overall health and color.

FAQ - Supreme Grass Seed Mix

Is Kentucky bluegrass shade tolerant?

  • Bluegrass needs about 70% sunlight throughout the day to stay healthy. If you have tried multiple times to seed a lawn under a tree with little success it may be that there isn’t enough sunlight for the bluegrass to sustain in that area. A better grass type choice would be turf type tall fescue because it can tolerate up to 80% shade.
