- Description
-
Sweet Autumn Clematis is easy to grow and can become invasive due to a rampant growth habit in addition to self-seeding. Prune aggressively in fall or early spring. This plant may be less frequently damaged by deer than other clematis species (hybrids).
The pinwheel flowers are fragrant and white with 4 petal-like parts and many stamens. The seed heads are feathery in appearance. Grow on a trellis or a fence. This belongs to pruning Group 3.
This plant is considered invasive in some states surrounding NC. Consider a native alternative.
