Cytisus striatus is a perennial evergreen shrub, (family Fabaceae) growing from 6-10 ft (2.0-3.04 m) in height. Like most plant in the Fabaceae family they have the ability to fix nitrogen. Young plants have an upright growth, but spread and branch as they mature. Stems have photosynthetic ability. Slender branches are covered sparsely by small leaves. C. striatus is native to northern Africa and southwestern Europe.
C. striatus leaves have from one to three leaflets. The leaflets are 0.3 to 0.5 in (5-15 mm) long. Leaves have short petioles on lower branches, becoming sessile as they rise up the stem. Leaves are more abundant at outer ends of actively growing branches.
The inflorescence of C. striatus consists of a cluster of 1 to 2 yellow pea like flowers on pedicels from 0.2-0.4 in (5-10 mm) long. Flowers are found in the leaf axils.
C. striatus fruit is a legume, 0.7 to 1.8 in (15-40 mm) long. Fruits are covered with dense white hairs. Each pod contains from about 5-9 seeds.
Ecological Threat
While the distribution of C. striatus is presently more limited than C. scoparius, they do occur in similar habitats and are believed to have similar ecological characteristics.
