Does anyone have a good resource on caring for the different groups? Pruning is my main concern, but am interested in any other information per group.
Clematis Groups?
http://www.clematis.hull.ac.uk/index.cfm
is a wonderful site. You can look up your clematis in the A-Z section, then when you find out the pruning group, click on the Pruning link and it will tell you how & when to prune for each group.

Is also a site I use, but I always start at the first link whenever I have to look something up.
