Due to its disseminatory reproductive system, vitality, and climbing behavior, Clematis vitalba is an invasive plant in many places. Some new tree plantations can be suffocated by a thick layer of Clematis vitalba, if not checked.
In New Zealand it is declared an "unwanted organism" and is listed in the National Pest Plant Accord. It cannot be sold, propagated or distributed. It is a potential threat to native plants since it grows vigorously and forms a canopy which smothers all other plants and has no natural controlling organisms in New Zealand.
