A traditional medicinal herb which is found in many old gardens, and is also occasionally grown for ornament. The plant grows into a small bush up to around 18 inches high with citrus-scented leaves, and is covered hundreds of daisy like flowers. It spreads, and they will cover a wide area after a few years in unattended. The Greek herbalist physician Dioscorides, in the first century AD, described it as an anti-inflammatory and to treat headaches and arthritis pain.
