Sweet Autumn Clematis: A Fall Blooming Beauty

Sweet Autumn Clematis is a fall blooming clematis with fragrant white flowers. Get growing tips, pruning advice, and ideas to keep it in check.

Several years ago, when we were still living at the house on Sutton Place, I had the idea to plant a Sweet Autumn clematis along the backyard fence. Like many garden plans, it never quite made it past the “someday” list. As luck would have it, my neighbor, Betsy, had planted one in her own yard. That summer, she tossed the top of the plant over the fence so I could enjoy it too. It was such a kind gesture, and that beautiful clematis turned out to be one of the highlights of my garden that fall.

Why You’ll Love Sweet Autumn Clematis

This variety of clematis truly shines when many other flowers have finished blooming. It begins flowering in late August and continues through September, sometimes even into early October depending on the weather. The dark green leaves provide the perfect backdrop for the delicate white blooms, which appear in clusters and seem to float along the vines. As the season progresses, the flowers transition into soft, silvery seed heads that look lovely in cut arrangements or tucked into fall décor.

Growing Tips

• Light Requirements: Sweet Autumn Clematis is hardy in zones 5 through 10. It grows in full sun, but a bit of afternoon shade helps produce more blooms and keeps the vines healthier.
• Provide Strong Support: this clematis is a vigorous grower. By the second or third year, it really takes off. A sturdy fence, arbor, or heavy trellis is ideal. Without support, it will creep along the ground, which isn’t ideal and can lead to it taking over nearby plants.
• When to Prune: this clematis blooms on new growth, so it should only be pruned after it flowers. Late fall or very early spring are the best times. Cut the stems back to about 18 to 24 inches before new shoots appear. This keeps the plant from getting too leggy.
• Patience Pays Off: it may take a couple of years for Sweet Autumn Clematis to bloom, but once it settles in, you’ll be rewarded with an abundance of fragrant white flowers year after year.
• Winter Dormancy: the plant is deciduous, so expect the stems to be bare in winter.
• Propagation: it can be propagated through root cuttings in the spring or soft vine cuttings in early summer.
• Seed Heads: One of the unexpected joys of growing this fall blooming clematis is the way it keeps on giving. After the blooms fade, the seed heads can be harvested and used in fall flower arrangements or dried for crafts.
