Scotch broom (Cytisus scoparius) is an escaped garden ornamental, common west of the Coast-Cascade
Mountains in southwest BC, and is concentrated at the southern end of Vancouver Island. Broom was
intentionally introduced to B.C. in 1850 by Captain Walter Grant who planted broom at his farm on
Vancouver Island. Regrettably, few realized the invasiveness of this perennial as it quickly spread
up the east coast of Vancouver Island before invading the Gulf Islands and mainland.

This weed is a strong competitor with various native plants including those within declining Garry
oak ecosystems as well as newly planted coniferous forests. It competes with native species for
available light, moisture and nutrients, especially on disturbed sites. So far there are no known
natural predators for this weed, therefore allowing it to spread throughout southern B.C. and other
parts of North America. Despite these detriments, Scotch broom is quite spectacular with its striking
array of bright flowers in spring. ~ Invasive Plants of Southwester BC
