Clematisviorna.info has been created to promote the appreciation and enjoyment of the North American viorna group Clematis species. It is my hope these species will be grown in botanic gardens, arboreta and will be made available for sale through nurseries.
The viorna group Clematis are superb native plants. They pose no pruning dilemma - all dying to the ground each winter, have no wilt problems, attract hummingbirds, and can be tucked into small gardens as well as large.
A few make great trough plants. Some are fragrant. All have attractive seed heads which give extended interest in the garden. About half of the species are small, non-climbing herbaceous plants while the remaining are vines.
I am indebted to all who helped with the site by use of photos and information.
