Clematis for the Frozen North!
The Atragene Group
Clematis in the Atragene Group all have several characteristics in common:
The Early Large Flowered Hybrids
These are the plants that most people think of when we say, "Clematis". They bloom in late May or early June and have large, flat flowers. Some will repeat bloom in late summer. Many are prone to a fungal disease called clematis wilt. We do not sell the varieties we have found to be susceptible.
Many authorities recommend treating early large flowered hybrids as "moderate prune" clematis. However, we disagree: Please see our Pruning Primer for more information.
The Late Flowering Hybrids
These clematis will flower starting in July. Expect a long bloom season from this group. Plants in this group are "full prune". Please see our Pruning Primer for more information. Late flowering hybrids are very winter hardy and very disease resistant. The flowers are flat and a little smaller than the early flowered hybrids. They make up for the difference in size by making lots of blooms!
The Kivistik Collection
The Kivistik Clematis were bred by Uno and Aili Kivistik at Roogoja Farm in Estonia between 1974 and Mr. Kivistik's death in 1998. The Kivistik's goal was to breed super hardy clematis that bloom on new wood. The Kivistik clematis are all quite short, rarely over 6 feet tall, and are bred to die back to the ground each winter. Although we list these plants as "Full Prune", most years all you will have to do is remove the dead stems at ground level.
For more information, see our Kivistik Clematis page.
The Viticella Hybrids
There are many, many clematis varieties that trace their parentage back to C. viticella
and most of them have several important characteristics in common:
The Texensis Hybrids
Yes, these plants are native to Texas. And, yes, they ARE winter hardy here, too - we've even seen them growing in Newfoundland! Flowers are upward facing, usually tulip-shaped and quite small. Full prune them in March. Give them a light, even gravelly, soil and full sun. Wilt resistant, although some varieties may be prone to mildew.
The Integrifolia Hybrids
Although these are a jumble of plants we couldn't fit elsewhere, they are all 'Full Prune" and appreciate a well drained soil. Grow one or more of these rare beauties and you'll really have a "Horse of a Different Color" in your garden!
