African rue is a perennial plant with a low-growing, bushy habit reaching 2 to 3 ft. (0.6-0.9 m) in height. The white, five-petal flowers are present from late spring to early fall in the axils of the leaves. Leaves are succulent, alternate, irregularly divided, 0.8-2 in. (2-5 cm) long and bright green. African rue is found in disturbed environments such as roadsides and fields in desert to semi-desert areas. The plant is found in many western states, although it may be extirpated from California. It is native to the Mediterranean and the Middle East. African rue produces primarily by seed, but severed roots can produce new shoots. The plant can be poisonous to people and livestock.
