Searching Category for CLEMATIS
We are utterly charmed with the North American viorna group of Clematis, and have decided to give them their own link on this website. This is a sweet group of small-flowered, urn-shaped species native to the eastern USA, sadly neglected in commerce and rare in gardens. The group is comprised of the following species: Clematis addisonii, albicoma, baldwinii, carrizoensis, coactilis, crispa, fremontii, glaucophylla, morefieldii, ochroleuca, pitcheri, reticulata, socialis, texensis, versicolor, viorna and viticaulis.

I cannot recommend too highly Carol Lim's wonderful "American Bells" site ( which has "been created to promote the appreciation and enjoyment of the North American viorna group Clematis species."

Carol states "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."

It's a lovely thought to imagine a day when all the species in the section might be represented here. Expect more additions over the next few weeks.


With some exceptions, Clematis seed are not long lived, even in optimum storage. During early to late fall of each year, we revise our listings, removing all stock from the previous season, and slowly replacing it with fresh seed, as it becomes available.

As I know many of you wait for the Clematis each season, rest assured that the list will continue to grow from October through December, with the same process repeating itself each season. Check back regularly, or write to ask about future availability of particular species.

CLEMATIS potanini ssp. fargesii New Summer-Fall893
2-5m  Zone: 4?
Very similar to the type species but shorter. The leaves are similar with leaflets more rounded or heart-shaped and more acutely toothed. Flowers are slightly smaller, but borne in larger lateral cycmes. Has a more northerly distribution in western China and might therefore be hardier.

CLEMATIS serratifolia New Late Summer905
to 3.6m  Zone: 4
Although superficially thought to resemble C. tangutica, this native of Japan and Korea has the form of C. alpina; opening into a wide nodding bell of clear yellow. Subtle lemon scent. This is a vigorous species which has its uses for that very reason, but care should be taken if self-sowing begins to become a problem.
Germination Instructions: Easy, warm germinator.

CLEMATIS virginianaLate Summer911
Virgin's Bower6m  Zone: 3
Native to North America with light green leaves and panicles of creamy white flowers. A common sight in our neighbourhood is farm fences and trees covered with a combination of Virgin's Bower and the annual cucumber vine: (Echinocystis lobata). The frothy effect of both is extremely lovely and satisfying. I like it as a sprawling groundcover over dead tree stumps or down a slope. Wild collected in Ontario.

CLEMATIS viticellaSummer913
Italian Vine Bower3-4m  Zone: 2
Considered by some to be the most trouble free and foolproof Clematis, this climbing species has been of prime importance in breeding since its introduction in the late 16th century. Free-flowering and vigorous, it will happily scramble through trees or shrubs. Blue nodding lantern-shaped flowers. Seed derives from an original wild collection.
Germination Instructions: Cold treatment required.
