Pruning spent blooms on clematis?

We have recently planted numerous (5) different clematis. One of them has a brillient green swirl of stems where each spent flower had been. Do we prune these off, or do leave them alone?Pruning spent blooms on clematis?
As Stuart said, leave them alone. Train the vines to go where you want only during the summer. In the fall after the leaves fall off don't touch the vines. They will become brittle and appear to be dead. In the spring they slowly come back to life. The ends of the vines will take the longest to get leaves back and stay brittle until this happens.Pruning spent blooms on clematis?
Leave them alone. They will continue to grow, and climb your trellis all summer.
