I hate turf... Get rid of it and put it all in wildflowers!
Sell the mower...
Failing to go with something so drastic... Leaves me curious... Do you mulch?
Teaching mowing crews to stay away from the woodchips is difficult, but if it's a family member mowing...
I'm a big fan of Chamaecrista fasciculata (partridge pea), When in bloom, it's an absolute hive of bee activity early in the morning... Unfortunately, it's too dark to get a good photo... or video.
Keeping with the fabaceae group... Maybe a dalea? They seem to grow in Iowa... I have dalea pinnata, and absolutely love it...
