The rushes as well as the sedges are large groups of plants that are related to grasses but have differences. This particular one is common in many places but it is very often overlooked. Its name is a really good one because it is often found next to all kinds of paths, including the dirt path along the Cynwyd Heritage Trail. It often gets mowed, but like the grasses, rushes can tolerate a bit of mowing, so it will grow back. It doesn't mind getting walked on. It doesn't make sod like grasses but forms a stiff tufty clump that will get a bit larger every year. 

It is very likely that you already have this growing on your property if you have any areas that aren't completely manicured. It will show up at the edges of driveways, flowerbeds, and garden plots. If you don't mow it off or walk on it too much, it will get 1-2 ft tall and produce a cute but small inflorescence. It may have some wildlife value; several sources indicate that animals eat the seeds but...they are REALLY small. In any event, we aren't making any special effort to cultivate this on the trail but enjoying it where it shows up. Formerly it was hard to find in the trade but it is becoming more popular as a possible substitute for a conventional lawn.
