Clematis, those flowering vines with blooms that are single or double, rounded or star shaped, large or petite, add so much charm to trellises, swirling around mailboxes, scrambling up a mature tree, draping over arches and arbors. To know them, is to love them. Here we are highlighting Group 3 clematis, which bloom later, often into fall.
It’s a huge family of plants (300+ species and hundreds of hybrids–typically divided into groups defined by bloom size and bloom time). We could go on about clematis for days–they’re that good. But we wanted to draw your attention to a few we recommend for late summer into autumn bloom.
Clematis are divided by bloom time into groups 1, 2, 3 (or sometimes A, B, C). The grouping determines when the flower will bloom and also when and how to prune. By planting clematis from all three groups you can have flowers for 5 months or more. ( More below on the different groups.)
The later bloomers, typically mid to late summer and into fall, are Group 3. If you plant these now, you will have some blooms this year and many more next, at a time when the rest of the garden is slowing down. Plant with other earlier bloomers and let them intertwine, or plant apart where the shock of the fresh blooms will be a total feast for the eyes. Here are 9 exceptional candidates for your garden.
We know this is a big topic and will do future posts about it (especially about pruning), but if you have clematis questions, do not hesitate to ask!
