African wood-sorrel

Native to South Africa, this highly invasive perennial plant has become a naturalized weed in many agricultural regions of the world. African wood-sorrel grows from a small bulb and the leaves that form a broad rosette of leaves at the base of the plant are divided into heart-shaped leaflets. Showy clusters of 5-petaled flowers develop on slender stalks. In Sicilian olive and citrus groves African wood-sorrel often grows in dense colonies that spread a glowing blanket of bright yellow blooms beneath the trees throughout winter and spring.
