Clematis 'Stand By Me' (Bush Clematis)
Another non-vining Clematis! This one will reach about 3' tall and be covered in beautiful purple to nearly blue flowers that hang down. No need to worry about how to prune this one either. It dies back to the ground each winter and comes back to bloom again the next. It will stand erect until the flower set pulls it down so a little support can be of good use. This is a cross between Clematis integrifolia and Clematis fremontii which are both non-vining as well.
