Gardeners' Notes:

Neutral northgrass On Aug 15, 2006, northgrass from West Chazy, NY (Zone 4b) wrote:

I had this clematis for many years and it has done just so-so for me. Some years it has just a few flowers or none at all. Maybe I expect too much by comparing it to my "Jackmanii' which has loads of flowers for at least 2 months. Marie Boisselot also does much better than this one in my garden.
The lack of blooms may be due that it blooms on side shoots from the previous year growth, although hardy, maybe freezing temperature does not help the flower buds.

Positive mystic On Jan 3, 2005, mystic from Ewing, KY (Zone 6a) wrote:

This is one of my favorites. Really stands out mixed in with other colors of vines. It's a good compact climber, the early blooms are sometimes tinged with blue. It blooms in late spring and again in the fall.

This was raised my Jim Fisk of Fisk's Clematis Nursery in England. He named it after one of his secretaries. Awarded RHS Award of Garden Merit in 1993.
