Clematis: Can you help me determine what kind of clematis this is?, 1 by doss

Looks like Rubens to me too although some of the others like Broughton Star look similar. Rubens is more common. Definitely it's a pruning type I but I believe that even if you give it a pretty hard pruning it will come back. It probably won't flower the following year if you do that. I planted some across my porch and to keep it in line I'm going to have to give it severe haircuts sometimes. It will get way too big for the place I have it in if I don't. However I haven't had to do it yet so only time will tell.

It's taken me 5 years to get the montana across this 16 foot spread so yes, it can be slow to establish.
