Feverfew

Tanacetum parthenium. Feverfew belonging to the family Asteraceae (daisies) is a daisy-like perennial plant found commonly in gardens and along roadsides. A short, bushy, aromatic perennial that grows 12 inches in height. Its yellow-green leaves are almost hairless, and chrysanthemum-like. Its yellow flowers bloom from July to October, are about 2 cm in diameter. The flowers resemble those of chamomile (Matricaria chamomilla), for which they are sometimes confused, and have a single layer of white outer-ray florets.

Feverfew also has been planted around houses to purify the air because of its strong, lasting odor, and a tincture of its blossoms is used as an insect repellant and balm for bites.
