To say this clematis is an active grower would be an understatement. Every year I cut it back aggressively, and every year it come back, plus more. I no longer worry about being careful in trimming during the summers. It gets trimmed when and where needed. This is not necessarily a delicate plant.
While the seeds and petals make a mess, the vine itself makes a great privacy screen during the summer. It becomes covered in small white flowers which insects seem to like. This would make a great screen, cover or addition to your garden if you have the room or are willing to trim it weekly.
Not all clematis flowers are the same color. Here is a great collection of varieties.
