Cytisus scoparium
Scotch broom is an invasive (non-native) perennial plant introduced to Oregon from Europe. It generally grows as a shrub and can reach a maximum height of 10 feet (3 m). The plant has multiple stems and few leaves, giving it a ragged, scraggly profile. The stems are darks green with a woody texture. It will produce hairy seed pods which are dark brown or black; and bright yellow flowers with five petals.
Due to the plant's highly adaptable nature, it can displace native species and thereby destroy natural plant communities. Its introduction to Oregon has been particularly impactful on forests and meadows. Additionally, Scotch broom seeds are poisonous to domesticated cattle who often use these areas for grazing.
The plant is often confused with gorse weed which is also invasive and has similarly colorful flowers.
Distribution
As an invasive species, Scotch broom can be found all over the Pacific Northwest. It can overtake any area with a recent soil disturbance and thus is found mostly along roadsides, pastures, meadows, grasslands, open areas and forested areas where logging or clear-cutting has occurred. Both state and federal agencies have policies and programs to help eradicate the plant, but due to its hearty nature, quick growth and the long viability of its seeds (up to 30 years), these efforts have had limited success.
Conservation Status
Common.
