Wild Quinine

American feverfew is a clump-forming, native perennial which occurs in dry soils on prairies, glades and rocky woods. Grows 3-4' tall. Woolly-looking, white flower heads, each with 5 tiny ray flowers (1/12" long), appear in broad, flat-topped, terminal corymbs from late spring to late summer. Leaves are aromatic, toothed and rough. Long-petioled basal leaves are much larger than stem leaves. Since the leaves of this species are in fact coarsely toothed, it remains an enigma as to why the plant was assigned the species name of integrifolium which means entire (i.e., margins lack lobes or teeth). Plant is also sometimes commonly called wild quinine. Former medicinal use as a diuretic.
