Clematis Sweet Autumn

Sweet Autumn Clematis

Clematis ‘Sweet Autumn’ is a vigorous, late-flowering clematis beloved for its clouds of small, fragrant white blooms that appear from late summer into mid-fall. Each star-shaped flower may be tiny on its own, but together they blanket the vine in a shimmering veil of white, filling the air with a sweet, vanilla-like fragrance. This spectacular late-season display attracts bees, butterflies, and other pollinators at a time when nectar sources may be dwindling. The lush green foliage provides excellent coverage, making this variety ideal for screening or quickly greening up vertical spaces.

Its rapid growth and ability to climb large structures such as pergolas, fences, arbors, or even small trees make ‘Sweet Autumn’ a standout choice for gardeners looking to create dramatic impact. This hardy vine performs best in full sun to partial shade and tolerates a wide range of soil conditions. Though vigorous, it remains easy to manage with annual pruning and quickly rebounds each spring. With its intoxicating fragrance, fast growth, and generous flowering habit, ‘Sweet Autumn’ clematis is a must-have for gardeners wanting a spectacular late-season show.
