- Ulex europaeus is an evergreen, perennial shrub native to Europe. Plants can grow from 3-6 ft. (1-2 m) in height. Shoots are covered with reddish-brown to grey hairs.
- Leaves are spine-like and 0.25-0.75 in. (0.6-1.9 cm) long. Mature shrubs have 1 in. (2.5 cm) long spines on the branches.
- Flowering occurs from winter to early spring, when shiny, yellow flowers develop in the axils of the leaves. Flowers are 1.0 in. (2.5 cm) long.
- Fruits are hairy, 0.5-1 in. (1.3-2.5 cm) long pods.
- Ecological Threat
- U. europaeus was introduced into North America in the mid-to-late 1800s as an ornamental. Plants invade gravel bars, logged areas and other disturbed areas. U. europaeus cannot tolerate extremely dry areas or areas with extreme temperatures.
