General Characteristics

General: Sunflower Family (Asteraceae). Wild quinine is a perennial, herbaceous forb. Stiff, upright, sometimes hairy stems are single, or branched near the top. Stems (4-12 dm in height) grow from a swollen tuberous root. The leaves are ovate to lanceolate with wavy, toothed margins. Basal leaves are 38 cm long. Stem leaves are alternate, smaller, and sparsely distributed along the stems. The long-lasting, somewhat-yarrow-like flower heads are composed of grayish-white, globular, compound flowers that are 4-6 mm wide. Five, unusually short, ray flowers (1-2mm long) surround the central disk flower corollas, which are 2.5-3 mm long. Only the ray flowers are fertile. The heads are grouped together into an inflorescent spray up to 20 cm in diameter. Flowers have a pleasant but mild medicinal fragrance. The plant flowers from summer through the autumn months.
