Gardeners' Notes:


On Aug 16, 2014, coriaceous from ROSLINDALE, MA wrote:

A hybrid between C. vitalba and C. fargesii (now usually called C. potaninii var. fargesii), combining the best of both---the lightness of growth and lovely flowering habit of the latter with the hardiness, vigor, and free flowering of the former without its smothering density and bulk.

Most people find this cultivar to be fragrant. I think of this as a much improved sweet autumn clematis, with a longer season of bloom and no self-sowing.

'Paul Farges' is the cultivar name. SUMMER SNOW (all caps) is a non-proprietary trade name. Still sometimes called by the botanically invalid name "C. fargesioides" in commerce.

vigorous, seems drought tolerant. I have it planted on the south side of a 6 foot fence in crummy unimproved clay on a slope. Grows up rapidly into the sun. Pruning group 3.
