All are very winter hardy and extremely disease resistant.
They belong to the "Don't Prune" group.

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:

They are all quite tall, usually between 8 and 12 feet.
They produce huge quantities of relatively small flowers.
Many are downward facing and at least a little bell shaped.
They are extremely disease resistant and winter hardy.
All should be ‘full pruned’; cut back to 12 to 18 inches tall in March.
They are great choices for beginners.

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

C. integrifolia and its hybrids are non-climbing clematis; they will sprawl unless provided with support. Most grow 3 to 4 feet tall and usually have the downward facing bell shaped flowers. Many varieties are fragrant, especially when planted in full sun. They are virtually wilt free, although they are sometimes prone to powdery mildew.
