A high-climbing vine that ascends by clasping leaf petioles or leaf rachi.
The leaves are compound, in groups of three leaflets. Its growth habit (vining) and flowers are very similar to those of Sweet Autumn Virginsbower, an invasive non-native plant. The two species can be easily separated based on the leaves, however. Devil's Darning Needle leaves have toothed margins, whereas leaves of Sweet Autumn Virginsbower are entire.
This plant is easily found in late summer in disturbed areas, such as along roadsides, streams, and powerline rights of way, and along forest edges. It grows throughout most of Maryland.
Host plant for Clematis Clearwing Moth.
