Is it a weed?


Ontario Nature

Published on Sep 18, 2014

Originally from Eurasia, dog-strangling vine (DSV) was brought to North America in the mid-1800s. In recent years, the vine has spread rapidly throughout central and southern Ontario, invading ravines, hillsides, fence lines, roadsides, utility corridors, and natural habitats including alvars and forests. DSV seeds are spread by wind and new plants grow rapidly from root fragments. This reproductive success, paired with the lack of predators, makes DSV difficult to control. In this short video, horticulturalist Paul Zammit demonstrates how he manages DSV at Toronto Botanical Garden. Ontario has an early detection and distribution mapping system called “See it, report it!” Submit invasive species sightings on the website or using their free app:
