Description: Branched large shrub up to 3 m tall. Well developed root system. The branches are erect, bushy in appearance, dark green in color. The leaves are sparse, small and fall off in mid-spring, so the stem performs photosynthesis. The flowers are yellow, butterfly-shaped and have a pleasant scent. They are gathered in clusters. The fruit is a flattened almost black pod.

Flowering time: May-August

Habitat: Dry soils with moderate climate

Interesting fact: Mildly poisonous species. Baskets (Spain and France) can be woven from the stem.
