Not a clematis person but saw this post and decided to chime in. Pic of a 'Sweet Autumn' or that is what it is supposed to be. Planted from some gift stub vines with roots about midsummer last year. Grew slightly and had a few fragrant blossoms during early fall. Frame is the basic frame from a metal patio glider placed under an unused 3 wire clothes line. Put up the stone border and filled with fine bark mulch a couple of days ago. This plant grows like crazy but, so far, has not put out suckers as an invasive plant would.
