I like lawns, and also enjoy mowing. Our lawn is whatever the surrounding field grass is - we never planted it, just started mowing the surrounding area as we were building our house, then slowly dug out garden beds.

I rarely water or fertilize the lawn and it looks pretty good until the dog days of summer. I have fond memories of my Dad jumping for joy when his urban lawn turned crispy brown in late summer and he could retire the lawnmower for a month or so.
I consider dandelions and clover as my lawn flowers, along with English daisies and spring crocus I purposely planted/
