Clematis virginiana, commonly known as Devil’s Darning Needles, Devil’s Hair, Love Vine and Woodbine, is native to north east USA, including Virginia. In its native habitat it grows at the edges of woodland, damp slopes and within scrub.

The etymological root of the binomial name Clematis is derived from the Greek klema ’vine shoot’, alluding to the climbing habit of the species. Virginiana is derived from the Latin meaning ‘from Virginia, USA’.

The landscape architect may find Clematis virginiana useful as a fast growing fragrant climber. It may be used to scramble over unattractive structures.

Ecologically, Clematis virginiana flowers are attractive to pollinating insects.
