Spiny broom


In spring, this densely branched, spiny shrub with 3-parted leaves is blanketed with masses of bright yellow flowers. It grows to 6 ft (2 m) tall, and may be seen as a single specimen, in small groups and often in large spreading colonies. Bacteria which form nodules on the roots of this Sicilian native fix atmospheric nitrogen for the host and nearby plants. Grows on dry, rocky slopes and hillsides with full sun exposure.

Scientific name: Calicotome villosa
Italian common name: Calicotome
English common name: Spiny broom
