One of the first things I planted in our gardens was a couple varieties of clematis. They grew like crazy. We had tall trellises and even those bowed under the weight of the early vines. It was so dense that one year we had a bird make a nest there! We really enjoyed carefully watching from inside the house as mama came to feed the babies. Eventually, however, the vines got to be such a jumble that I cut them down and started over with shorter trellises. That was all before we went to primarily hostas, daylilies, asian lilies and sedum, but they still come back every year and bloom a few times. They starting blooming again in the past few days.
Every spring I end up plucking out multitudes of clematis volunteers, but the blooms are just so pretty that they have earned a permanent place in the garden.
