Blackened crispy leaves are often due to a common fungal disease called clematis wilt. Large-flowered clematis are more prone to clematis wilt than the species and small-flowered hybrids.

Clematis and tomatoes are two exceptions to the usual rule, and are best planted 6 inches deeper than the soil level in the pot. This protects the stem bases from mechanical damage, and helps prevent clematis wilt, whose fungus enters where there's damage. It also helps keep the roots cool.

Many small-flowered hybrids are spectacular in flower, and long-blooming. I consider them indispensable, especially th... read more

Awesome 7" violet, almost blue blooms with 8 petals pointed at the tips. The petals have a faint silvery center stripe laid on top of the viotet color, giving it a fascinating metallic finish.

I have had this plant for 3 seasons and I love it. I have trained it to grow up a fence which faces east. Currently have 21 open flowers, and 32 unopened buds as of 4/27.

When I fertilize my roses (Rose Tone), I usually throw some at the base of The President also.

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.

I have 'The President', along with 'Josephine', 'Niobi', 'H. F. Young', 'Multi-blue', and two new ones I just put in the ground this year.

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