Status:

Sweet Autumn Virginsbower is an invasive plant from Asia. This exotic clematis has escaped from the plant trade and has become established across most of Maryland. Sweet Autumn Virginsbower forms dense mats of either climbing or creeping vines that choke out all other plants that are growing underneath.

Description:

Superficially resembles our native Virginia Clematis but the leaves of our native clematis are typically cleft or coarsely toothed while the leaves of Sweet Autumn Virginsbower are smooth and entire. The seeds of Sweet Autumn Virginsbower often appear more feathery than the smoother seeds of Virginia Clematis.

Where to find:

Sweet Autumn Virginsbower grows along hedgerows and forest edges and other open or semi-shaded habitats.

There are 344 records in the project database.
