Rue is a biennial or perennial herb widespread in arid areas of southern Europe and North Africa. It has sparse leaves with two to three buds and yellow flowers (May to July) with a strong characteristic odor. It grows to 0.5 m (20 in.) in height. Several other varieties of rue are known, including R. bracteosa, R. montana L., and R. calepensis. The parts used are the leaves and fresh blooming plants. Rue has an herbaceous odor (fruity, orange note) and a sharp, burning, acrid taste.
