In my neighborhood, there are quite a few wooded lots, where they just let the trees grow with varying levels of deliberate gardening under the trees. It's quite pleasant.
My neighbors have something like that in their back yard, and prairie grass in the front. My house has a big vegetable garden, some flower gardens, some bushes, and trees. We also have some lawn, but it's un-maintained and only needs to be mowed a couple times during the spring before it goes dormant. It's also about 1/2 weeds. Every year we convert more of it to garden.
Only about 1/5 of the houses have actual managed green lawns.
Contrast with my parents' neighborhood in another state. Every lawn in the entire 'hood is bushy bright green, and the people are out there mowing all the time. Many of their neighbors mow twice a week. One neighbor had a large mature tree cut down because it was shading their grass. Of course you can't see the lawns because all of the streets are lined on both sides with giant cars.
In addition to the visual appearance, there's the noise. A relative of mine went on vacation recently, to a place that was more or less off the grid. His comment was that there were no string trimmers or leaf blowers. A lot of suburban neighborhoods are just a constant racket of equipment.
I get it, it's a culture thing. But it's interesting to see that there are actually lots of possibilities for what to do with the grounds around a detached house.
