A hybrid of C. 'Fortunei' x 'Jackmanii'.
Developed by Charles Noble in 1873.
The variety has received the Royal Horticultural Society's Award of Garden Merit.

A fool proof repeat bloomer w/ 8" flowers.
More tolerant of shade than many Clematis.
Will even bloom in North facing sites.

Ours have been in the ground for 2 years now,
from bare-root, and are about 7' tall now.
We have had about a dozen blooms.
Should bloom heavily next Spring.
