American Feverfew (Parthenium integrifolium)

     American Feverfew is a native, perennial wildflower that can reach three feet in height. It has white, fuzzy flower clusters that are about 1/4 inch wide, with tiny ray florets and purple markings on the banner petal. The flower clusters are flat-topped or slightly rounded. The leaves are aromatic, leathery, and hairy, with coarsely toothed or scalloped margins. The basal and lower stem leaves are elliptical to broadly ovate, and taper into long petioles. The upper stem leaves are smaller and sessile, or without stalks. American Feverfew grows in dry to medium-wet soils, in full sun or partial shade, in habitats such as prairies, glades, and rocky woods. (July)
