Description: |
Gorse is a dense, spiny, evergreen shrub resembling Scotch broom in appearance. It grows up to 10 feet tall with upright, angular stems that change from green to brown as they mature. Its spreading branches end in sharp spines and have stiff spine-like leaves about 2 inches long. Leaves have 3 thin leaflets which become spiny as they mature. Spines are also found in the leaf axils. In February its yellow, pea-like flowers begin to bloom. Flowers grow in clusters near the ends of branches. When ripe its hairy, brown seed pods burst, spitting seeds up to several feet. Seeds are smooth, shiny, and olive green to brown in color. |
Why Is it a Noxious Weed? |
Once established, Gorse spreads rapidly, crowding out other plants and forming dense thickets. Gorse has a high oil content and a growth pattern of dry, dead vegetation at the center of the shrub. These two factors create a serious fire hazard. |
Where Does it Grow? |
It grows best in sandy or coarse, gravelly soil. It likes gravel bars, fence rows, river banks, open areas and grasslands. From there it has the ability to encroach upon agricultural or recreational lands. |
Facts: |
This plant produces seeds prolifically; the bursting seed pods scatter seed for several feet. Animals, machinery, and water also carry the seed. Seeds remain viable in the soil for up to 40 years. |
