A SPECIES OF: Tansies

ALSO KNOWN AS: Pyrethum Daisy, Garden Pyrethrum, Persian Insect Flower, and Feverfew

BOTANICAL NAME: Tanacetum Coccineum

DESCRIPTION: It is a perennial plant native to Caucasus and looks somewhat like a daisy. It produces large white, pink or red flowers. The leaves resemble those of ferns, and the plant grows to between 30 and 60 cm (12 and 24 in) in height. The flowering period is June to July in temperate climates (Northern Hemisphere). C. coccineum also contains insecticidal pyrethrum substances, but it is a poor source compared to C. cinerariifolium.

INTERESTING FACTS: Pyrethrum has been used for centuries as an insecticide, and as a lice remedy in the Middle East (Persian powder, also known as "Persian pellitory"). It was sold worldwide under the brand Zacherlin by Austrian industrialist J. Zacherl. It is one of the most commonly used non-synthetic insecticides allowed in certified organic agriculture. Because pyrethrum contains pyrethrins and aphid alarm pheromone, they are used as companion plants to repel pest insects from nearby crops and ornamental plants. They are thought to repel aphids, bed bugs (Cimex lectularius), leafhoppers, spider mites, harlequin bugs, ticks, pickleworms, and imported cabbage worms, among others, in gardens and farms. For example, they are planted among broccoli plants for protection from several common insect pests. The alarm pheromone both attracts ladybug beetles and repels aphids.
