Yes, it does. But not all grass in Kentucky is bluegrass. Bluegrass grows heavily in the central part of the state, and becomes more sparse in the further areas. When you're in an area where all the grass is bluegrass, you can't tell that it's bluegrass, because it really is green. But - in parts of the state where the bluegrass is more sparse, you can look out over a grass-covered area and notice that certain patches have a blue-ish tint. Then can you really tell the difference in bluegrass and green grass.
