It is a grass that I find annoyingly patchy as lawn but wonderful as a garden plant. There it runs in between the fans and sometimes sets deep between them. I use a hoe, hand spade and, where set deep in between the fans, Round Up by rubbing it onto individual grass stems manually. Just ensure the stuff doesn't get on the daylily, which you can avoid if you doing it carefully with individual attention.
However, it comes back like all excellent weeds.
