Feverfew (Parthenium)
Feverfew Genus Details
A member of the composite family, feverfew grows in open fields and plains from New York to Georgia. Alternate leaves are ovate and can be up to 8" long. Feverfew can grow to 4' tall. The small flower heads have yellow disc flowers. White-toothed ray flowers are around the yellow-center disc. A tincture made from feverfew and applied locally relieves pain and swelling caused by bites from insects and vermin. If planted around buildings, it is said to purify the atmosphere and ward off disease.
