My favorite autumn flowering vine

I want to show you what I see when looking out from my kitchen window. I think they are called  ,Sweet Autumn Clematis but not sure. they bloom profusely every Fall. I was given a start of this from my neighbor and sure do enjoy it!. I was afraid I had killed it this spring as I cut it back almost to stubs..goes to show what a prolific grower it is! Also, the bees and butterflies are loving it!
