Tanacetum parthenium

Feverfew is a composite plant, a hardy biennial to perennial with alternate leaves, covered with soft short hairs or may be almost smooth, 8-10cm long and 3-6cm across, bipinnatifid, with serrate margins, the leaf-stalk is flat on top and round beneath. The leaves differ from those of the otherwise similar Chamomile, whose leaves have a feathery appearance. An upright plant, it can grow to a height of 25-50cm and has many, small, daisy-like yellow flowers arranged in tiny flat clusters and surrounded by a circle of white rays, the whole being no more than 2cm across. The stem is hairy and finely furrowed. The seeds are brown, tiny, and numerous. All parts of the plant have a strong bitter smell and taste.

A plant of European origin, it has naturalized in many areas of North America and is a common volunteer in flower beds. Once planted, Feverfew requires very little care. The best time to plant is around the end of April. Almost any soil will suffice but best is a well-drained loamy mix, treated with rotted manure. It grows easily from seed, cuttings, and root division. Seeds are best sown indoors February and March, then planted out in June. Divisions may be made any time the roots are active, and cuttings may be made from young shoots from the base of a plant at any time. Cuttings must be shaded and well-watered while rooting. This plant is susceptible to snails, slugs, and black fly. Pepper spray will deter the flies and ashes or lime sprinkled around the plants will stop snails and slugs. Mrs. Grieve makes the delightful suggestion to place half buried flower pots on their sides to attract toads to your garden as pest control. The leaves may be harvested through spring and summer but quality is best just before the flowers open.
