Pyrethrum Daisy (Tanacetum cinerariifolium) is a species of flowering plant in the aster family, Asteraceae. It is a perennial plant with numerous small white daisy-like flowers with a spicy scent, and is related to both Feverfew and Tansy. It is native to Europe and the east Adriatic coast. Formerly part of the genus Pyrethrum, but now placed in the genus Chrysanthemum, or the genus Tanacetum. It is also called the Dalmatian chrysanthemum.
The flowers are cultivated commercially as a natural pesticide and fumigant. The flower buds are picked when they are in full bloom, as this is when they have the highest pyrethrin content. A good insect repellent for the garden. Flower heads are dried and powdered for use as an insecticide. Pyrethrum paralyses insects but has little to no effect on mammals.
Common Names: Persian Insect Flower, Pyrethrum and Pyrethrum Daisy.
