Common gorse is an introduced European species of disturbed sites, grasslands, forest edges and coastal bluffs that is now found in North America along the Pacific Coast, and in several New England states (US--CA, HI, MA, NY, OR, PA, VA, WA, WV; CAN--BC) (USDA 2010). In British Columbia, it is found in the southwest corner of the province with some records from the Queen Charlotte Islands. It is a perennial yellow-flowered shrub with spine-tipped branches that ranges from 1-3 m tall. Branches are noticeably 5-angled. Fruits are pods. Seed have a hard, water-impervious coat that can delay germination (Global Invasive Species Database 2010). Infestations of this species can result in impoverished soil (Global Invasive Species Database 2010).
