- Pictures
Identification: Perennial; blooms April to June. Grows 3 to 10 ft tall. Similar to Scotch broom except stems thicker and rougher, it has very few leaves, and flowers larger and fewer in number.
Impacts: The least abundant of weedy brooms in Oregon, Spanish broom is adapted to dryer sites where its lack of leaves and thick waxy stems resist dessication. Like other broom species, it offers strong competition to other plants and contributes to increased maintenance costs on lands where it becomes established.
Biological
Controls: One approved biocontrol agent, a beetle who feeds on seeds in the larval stage and pollen in the adult stage, has become established in Oregon but is threatened by a parasitic wasp.
