Feverfew

(Tanacetum parthenium) Feverfew is a half-hardy perennial member of asteraceae, or daisy, family. Longer stemmed varieties make perfect cut flowers, and it is excellent in the landscape, ideal for borders, mass planting and containers. The long-lasting blooms are abundant and fill in a space with tufts of subtle color. This beautiful medicinal plant has traditionally been used to treat headache. It is grown as an annual in most zones and is perennial in USDA zones 5 to 9. Plants prefer full sun and need well-drained soil. Start seeds indoors 4 to 6 weeks before last frost, or direct seed into the garden when the threat of frost has passed. Ideal germination temperature is 70F. Seeds germinate in 10-20 days. Surface sow, as light aids germination. Plant 8 to 12 inches apart.
