Clematis 'Golden Tiara'

Clematis 'Golden Tiara'

A corker! Oh, how she flowers!
And therein is the problem. Wrong place. I have given it a strong support but it overflows and is simply far to vigorous. It takes over and simply swamps!
It has to be moved. Not a task I relish. Maybe I will wait until it has finished flowering...
What could replace it though? So many choices, so little space!
