Wild Flowers of Pittsburgh

Feverfew (Chrysanthemum parthenium)

A garden favorite that sometimes makes itself at home here, especially in the city. This plant was blooming on a bank in Beechview in early June. Feverfew is named for its supposed fever-reducing effects, though modern science has looked for those effects and failed to find them. The cheery flowers are like generous clusters of small daisies.

Botanists often place this species in the genus Tanacetum with the Tansies, but it is most familiar under the name Chrysanthemum, which is where Gray puts it:

CHRYSANTHEMUM [Tourn.] L. OX-EYE DAISY. Heads many-flowered; rays numerous, fertile. Scales of the broad and flat involucre imbricated, with scarious margins. Receptacle flat or convex, naked. Disk-corollas with a flattened tube. Achenes of disk and ray similar, striate. — Annual or perennial herbs, with toothed, pinnatifid, or divided leaves, and single or corymbed heads. Rays white or yellow (rarely wanting); disk yellow. (Old Greek name, Chrysanthemon, i.e. golden flower.)

C. parthènium (L.) Bernh. (FEVERFEW.) Tall, branched, leafy; leaves bipinnately divided, the divisions ovate, cut; rays white. — Escaped from gardens, and naturalized in some places. (Introd. from Eu.)
