After I posted "Plants not Lawns," I heard from turfgrass growers, their national association and a landscape company. One of them very kindly pointed out that turfgrass is a plant and, in fact, is classified as an ornamental nursery product by the Department of Agriculture. I have to admit that I thought of lawns as the equivalent of living carpets instead of as a durable and foot traffic-friendly groundcover plant. The average size of a lawn in the US is one-fifth of an acre. In a healthy lawn, there are six grass plants per square inch and 850 plants per square foot. I did the math: an average US lawn contains 7.4 million plants!
Turfgrass lawns provide many of the same functional and aesthetic benefits as trees:
