My husband and I found scattered clumps of this grass growing along the edges of the woods at the back of our property and in some of the flower beds. Once we found it I did research to determine what kind of sedge or grass it was. I believe it is Openflower Rosette Grass
(Dichanthelium laxiflorum). My question is would it make a good border plant in place of liriope along the edges of a semi shaded flower bed? Or would that turn into a weeding nightmare?
