Scott Broom (Cytisus Scoparius) , while pretty in color is an invasive species that was originally introduced from Europe as an ornamental plant that could be used for erosion control. Being a prolific seed producer, 18,000 seeds per plant, this species has spread quickly throughout the Pacific Northwest. In the process, this plant has had an adverse effect on the revegitation of upland sites, wetland buffers and attempts at reforestation. The costs to the states to control and remove this plant is in the millions each year. In the photos, one can see this plant in different stages, a flower, a single plant, a few plants and then a total colony on a hillside.
