Scotch broom (Cytisus scoparius)

Scotch broom

Cytisus scoparius


  • Yellow pea-like flower sometime with a red marking in the middle
  • Grows 1m to 3m tall and has a green woody stem
  • Tight against the stem are seedpods that are initially green and turn brown to black as they mature

Consequences of invasion

  • Fire hazard
  • Obstructs driver views on roadsides
  •  Takes over rangelands and plantations resulting in decreased crop yields and plantation failures

How is it introduced? How is it spread?

  •  Transported by travelling on machinery and vehicles
  •  When seed pods burst, the seeds can travel up to 5m, and easily take over land with disturbed soils

Integrated Pest Management Options

  • Become Plantwise and learn about Grow Me Instead
  • Avoid having areas of disturbed soils
  • Minimize soil disturbances and plant competitive shrubbery such as snowberry, salmonberry, thimbleberry or Oregon grape
  • Scotch broom can be hand-pulled although this can disturb the soil and lead to further infestation. Cut the plant stem as close as possible to the ground and cover the stub with a secured plastic bag to prevent exposure to sunlight. Roots are photosynthetic and will regrow if exposed to sunlight
