ROO-tah
Rutaceae
Eight or so species of shrubs and perennials from dry and rocky habitats belong to this genus. The leaves and flowers are very strongly scented. Foliage is very tiny, sometimes bluish green, and finely cut. Historically, rue was used in cooking or medicinally. The flowers are unusual looking and yellow, and borne at the end of stems. Leaves have a bitter taste and are toxic.
Noteworthy characteristics:  Aromatic leaves and flowers. All parts of the plant may cause severe discomfort if eaten and the foliage may cause severe dermatitis. Thrives in hot, dry sites.
Care:  Grow in full sun or partial shade in moderately fertile, very well-drained soil.
Propagation: 

Propagate from semi-ripe cuttings in summer, or sow seed in a cold frame in spring.

Problems: 

Generally trouble-free, but Phytophthora root rot can sometimes cause problems.
