About
Small, thorny leguminous shrub with yellow flowers, typical of acidic and poor soils of the Iberian Peninsula. Fixes nitrogen in the soil through root symbiosis and forms protective thickets. In the agroforestry system, it occupies the shrub layer, contributing to fertility and serving as a refuge for beneficial fauna.
