Feverfew is a bush-like perennial that averages 18 inches tall, but has been known to grow twice as large. The leaves are feathery with white and yellow flowers that bloom in July and October. This is a self-seeding plant that can reproduce quickly; removing the flowers will limit reproduction. Feverfew grows in partial shade or partial sun and tolerates most well-drained soils.
It is believed that feverfew controls the release of serotonin and prostaglandins, which can cause migraines, and by limiting the inflammation of blood vessels in the head and reducing blood vessel spasms, headaches and migraines can be reduced. Feverfew has also reduced redness of irritated skin. Traditionally, the plant has been used to treat menstrual and labor difficulties, as well as stomachaches.
