This is the only large-flowered clematis I've had success with in my years of trying to grow them here in North Texas. It must be in the right spot -- the roots receive no direct sunlight and the foliage only receives morning sun. It grows wonderfully amongst my 'Kathleen' climbing rose!

My neighbor and I both bought this clematis this spring and planted in good spots. Mine withered up and died a slow death within two months. My neighbors is doing the same. I've always had good luck with clematis but generally buy them very small. This was a very big plant in full bloom when I got it.Too bad, it had a beautiful bloom.

The president is a trooper. It does benefit from being cut back strongly in early spring. Flowering is delayed but the plant gets bushier and more resilient.

My plant is now about 6 years old. I was hoping for more flowering; I don't know about cutting it back.
