The Problem
- Can take over riparian areas changing or stopping water movement
- As an annual it provides less protection from erosion after it dies back in the fall
- Prolific producer of nectar may draw pollinators from native plants
Distribution
- Partially shade tolerant, found in moist or riparian areas
- In NB found mostly on the Fundy Coast, also starting to spread in Fredericton
- Distribution is limited in Eastern North America
- One of the worst 20 invasive plants in the UK and also on the radar in Western North America
