Neutral | On Mar 7, 2016, coriaceous from ROSLINDALE, MA wrote: 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. http://www.missouribotanicalgarden.org/gardens-gardening/you... |
Positive | On Apr 27, 2012, whalloper from Bear, DE wrote: 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. |

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! |

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. |
Positive | On Jun 12, 2005, teatimer from Lavrica, 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. |
