If you want to see individual blades of grass, you have to use a 3D grass model. I found one in the Sketchup Warehouse, which I modified heavily (mainly reducing the size of the images). Even when I managed to reduce the overall size by more than 50%, you would still add approx. 1 MB for 1 m2 of grass. Not counting the inevitable delay in rendering. Here is another one which you will have to convert to DAE format.
