Rue is a highly aromatic and decorative evergreen shrub-herb. It is a member of the Rutaceae family (citrus). It has lacy blue-green leaves, small yellow flowers and grows to a height of about 90cm. Although native to Mediterranean, this perennial herb will tolerate cooler climate and it makes an attractive hedging plant growing also for its (almost entirely) decorative qualities.

Rue has been highly valued for its medicinal strengths over the years. It is reputed to cure numerous complaints, such as headaches, coughs, and croup. Rue is toxic in large doses, but it is prescribed by Homeopaths in minute doses to treat symptoms of weakness or bruising.

The part of the plant used (in very small quantities) is the fresh leaves to flavor salad dressings; if fresh leaves are not available, using the dried leaves make a poor replacement. Rue has a strong fragrance that is pleasant and sweet. Its rather bitter taste is , even more bitter when dried.

The herb prefers full sun and well drained soil with natural or added lime. Propagation is by seed, root division or cuttings 10-12cm long, in late summer. Many centuries ago rue was taken medicinally as a tisane and thought to preserve good health.
