Compact non-invasive grass for clay soil
Can you please recommend a compact (max 3') non-invasive ornamental grass that could grow in clay soil in zone 6?
I have a lot of "mounding" and round perennials so I would like something vertical or spiky for contrast. It will be up against the green leaves of a landscape rose so something coppery or burgandy would be nice. Also I'd like to plant it in the fall, if that's possible.
