Gardeners' Notes:


On May 19, 2011, CanyonRoad from Colorado Springs, CO (Zone 5a) wrote:

"Willy" has grown very well for me on a six-foot high chain link fence in partial shade. The flowering period is short, only a couple of weeks in May, but the little lavender-pink pendant flowers are delightful, somewhat resembling fuchsias. I almost lost Willy during a period of drought several years ago, but it has slowly recovered and is making itself at home again. It does need constant moisture to do well here.

This vine grows very well on the north side of my home in zone 8 with the rambling rose "Darlow's Enigma." I look forward to seeing both in bloom each year. First the Willy clematis in the spring, and then the rose all summer long.

I grow this one next to Pamela Jackman and the blue vs pink contrast is wonderful in June. Very floriferous. I also grow this one up through a chokecherry and when it blooms, it seems the flowers are from the cherry!
