ALERT SPP This Plant is on high alert.
Latin Name: Cytisus scoparius
Physical Description: Shrub with erect ribbed stems that extend up to 3m tall. It has yellow pea-like flowers. New stems are green and hairy and become woody as they mature. Leaves at the base of the branches have 3 leaflets that are alternately arranged.
Habitat: Prefer mesic to dry areas and can be found in grasslands, shrub lands, woodlands, riparian corridors, roadsides, pastures, burned areas and cleared forests.
Impacts: Forms dense stands that is unpalatable to wildlife and impedes movement. The accumulation of wood biomass poses a fire risk. Flowers can be toxic to humans, wildlife and live stock when consumed.
Reproduction: Seed only. Seeds (5 to 9) are ejected from mature seed pods. Seeds can remain viable in the soil for up to 30 years.
Mechanical: Seedlings and shrubs can be hand pulled or dug out. It’s important to remove all of the root to prevent re-sprouting from occurring. Cutting mature plants before seed production can reduce seed production and deplete the plants energy reserves.
Chemical: Several herbicides with the following active ingredients can control Scotch broom: picloram, triclopyr, aminopyralid+ triclopyr, trycolpyr +2,4-D, glyphosate and triclopyr. For available products, contact your local agri-supply store. Prior to any herbicide application, read and follow the label instructions
