What is Broom?
Broom plants were introduced in California around 1850 as ornamental plants in gardens. Later, when the California highway system was developed, they were used to control erosion along road banks.
Broom is an invasive plant. This means it came to California from another area (Europe) and now competes with native plants for dominance, and the broom is winning!
Broom is an evergreen shrub with clusters of yellow flowers which bloom in late spring.
