Clematis - Jackmanii and Jackmanii superba

I have two Clematis growing on the south side of my deck. They are about 20 feet tall this year. I ran some cords from the second floor deck ceiling, and they climbed part the trellis up the cords. One of the Clematis is 'Jackmanii', and the other is 'Jackmanii superba'. They are different shades of deep purple, and the 'Jackmanii' flower is a little smaller with 5 petals, while 'Jackmanii superba' has 4 petals.

These are type 3 (or C) Clematis, so I cut them in late winter down to about 12'' from the ground.
They get daily drip irrigation. They don't like to get dried out (they'll quit blooming early).

For some of my other Clematis, I trim off many of the spent flowers. I think it may keep the plants blooming longer.
