Common Name: Yellow Clematis

Scientific Name: Clematis tangutica

Habitat: roadsides, disturbed areas, fence lines, ornamental beds, forests

Provincial Designation: Noxious

Noxious weeds are plant species that are designated as "noxious weeds" in the Alberta weed regulation. Noxious weeds must be controlled, meaning their growth or spread needs to be prevented.


Yellow clematis is native to high mountain areas in India and China and was introduced to North America as an ornamental garden plant.

Legislated Because

This climbing species can invade natural woodland areas by covering trees and bushes, weighing them down and damaging them. Yellow clematis is also known to smother and out-compete other vegetation.


The 4-6 cm wide flowers of yellow clematis are bright yellow in colour and are often bell-shaped and drooping. The leaves are deeply lobed or pinnate and have 3-5 leaflets. Each fruit has a long hairy plume and several fruits are clustered at the end of each stem, forming a white hairy ball typical to the species.

As a climber it grows on fences, posts, or other plants and can reach up to 4 m in height.
