Clematis occidentalis is known by the common names western blue virginsbower or purple clematis. It is native to much of southern Canada and the northern United States.

It has single blossoms that feature four petal-like sepals, which range from blue-violet to pinkish-purple. Within the centre of the flower is a prominent column composed of numerous stamens surrounding a bundle of styles. 

Clematis occidentalis produces plume-like fruit. The flowers transform into heads of finely hairy seeds, featuring elongated tail-like structures. 

Clematis occidentalis vines lack tendrils on its stems. The leaf stalks twine around surrounding vegetation and structures for support.

This Clematis is listed as rare or endangered in several states.
