Low height ground cover type plants grew naturally there. Clover, alfalfa, strawberries, unknown other plants, with an occasional thistle. Larger plants (whatever they were) would grow on the periphery. When he mowed my lawn it was maybe about a foot high.

We were surrounded by acres of forest where plants grew wild, so if there was a problem with pollen, it wasn't the .4 acres of my front lawn. Myt front lawn, I did mow occasionally. The back I let grow wild and yes, one could still walk through it.

One of the lame things about lawn is that people don't let them go to seed. If grass goes to seed, it not only regenerates itself, but also provides food for birds and squirrels. I was on an acre and a half across the street from this guy, and bounded by 30 feet of trees on ones side and 200 feet of forest on the other.
