- Description
-
Sweet autumn clematis is an aggressive, woody, perennial vine in the Ranunculaceae (buttercup) family and native to New Zealand. It grows rapidly in addition to self-seeding and is considered invasive in some states surrounding North Carolina.
It grows in full sun, dappled sunlight, or partial shade in moist soils with good drainage. This plant flowers only on new wood and can be cut to the ground in fall or spring.
The pinwheel flowers are fragrant and white with four petal-like parts and many stamens. The seed heads are feathery in appearance. Flowers attract pollinators and songbirds use the vine as a nesting site. This plant may be less frequently damaged by deer than other clematis species.
Insects, Diseases, and Other Plant Problems: Self-seeds and grows aggressively. Consider a native alternative.
