This publication from Montana State University Extension describes the biology, ecology, and management of Scotch broom. Scotch broom (Cytsis scoparius L.) is a highly invasive perennial shrub. It can be recognized by its bright yellow flowers, clover-like leaves, and shrubby growth habit. This species was introduced to the United States in the 1850s to control soil erosion and as a landscape ornamental. Scotch broom spreads rapidly and frequently outcompetes other plant species, especially in disturbed sites, pastures, roadsides and open woods. Control is difficult once this species becomes established, with repeated treatments often required. Scotch broom is currently limited to Sanders and Lincoln Counties in northwestern Montana, therefore prevention and early detection are key to its management.
