Clematis Tree?

Alas, it seems nobody has identified your 'Clematis Tree' LOL

Did it grow bigger. Did it have any flowers?

Nope, it went the way of the axe some time ago when it became apparent that it was not something my son-in-law wanted there. We had planted it at their place when I first had to move into an apt. It grew in leaps and bounds. In its place is a real Clematis that my son-in-law picked up on a close out sale and it is surviving and doing well and has buds ready to bloom.

Seems we'll never now know what it was...

.... unless there are any guesses .....
