Perennial.
Feverfew (Tanacetum parthenium) is 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 by flowers reminiscent of daisies. It spreads rapidly, and they will cover a wide area after a few years. Feverfew has been used for reducing fever, for treating headaches, arthritis and digestive problems.
