Such pretty Irises. I love Irises! Someone just gifted me a few as she was dividing an area in her yard. They are still in a clay pot in the alley, one of a few things I have left to get into the ground and/or pot up.
I think the reason all of that LIriope is out there is because it withstood the rain run-off and hid any rutting in the soil that the run-off caused. I am tempted to just put in more Liriope and be done with it, but it does not make for a pretty or interesting bed and is not very satisfying. I am also seriously considering stepping stones along there. Stepping stones should stop the ruts from forming and also give me a path to the front of the house.
