I'm not sure if this post should go here or in ornamental grasses yet I'm looking for suggestions of what I can use along a dry stream bed that will look like a carpet or mat of flowing grass rather than individual tufts or clumps. The first thing that comes to mind (probably because it is the only thing I know) is Japanese blood grass but it is the wrong color. I want something softer, green or variegated. The soil is clay-loam (ammended) with good drainage and Ph of 7. This has to live happily with Echninacea, Nepeta Fasseni and Karl Foerster. Oh and it will be planted on the North side of house - if it helps I'm in Medford, Oregon. Thanks!
