NC Rank 2 Invasive, Significant threat

"From the National Park Service website: "This species is found invading forest edges, right-of-ways and urban areas along streams and roads. It grows vigorously over other vegetation, forming dense blankets that block sunlight to the plants underneath. In late summer infestations are conspicuous as a result of its abundant showy white flowers."

Flowers

The flowers are fragrant. They are very similar to the native Virgin's Bower, Clematis virginiana, but the native clematis has mostly 3-parted leaves with toothed edges. In seed, the invasive Sweet Autumn Clematis has feathery styles. The styles of Virgin's Bower are smooth and threadlike.
