Sweet Autumn Virginsbower

Clematis terniflora DC
Buttercup family (Ranunculaceae)

Origin: Japan and China

Background
Sweet autumn virginsbower was introduced into the United States as an ornamental vine and is still widely sold in the nursery trade.

Distribution and Habitat
Sweet autumn virginsbower is documented to occur in much of the eastern U.S. from Minnesota to Vermont, south to Texas and Florida. It has been reported to be invasive in Alabama, Delaware, Florida, Georgia, Illinois, Maryland, New Jersey, North Carolina, South Carolina, Tennessee and Virginia, although it is probably invasive in additional states where it occurs. It prefers full sun but can tolerate partial shade.

Ecological Threat
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.
