Ruth Iowa DOT is "beginning" to use natives but there is still a lot of localized spraying of road ditches that have natives (can't tell one milkweed species from another) and "natives as groundcover" hasn't been embraced by all roadside managers or county engineers. Just last year we tried to convince a county engineer to plant natives but he had all sorts of arguments why he couldn't/wouldn't.
