A. vulgaris is native to temperate Europe, Asia, North Africa and Alaska and naturalized in North America, where it is considered an invasive herb. It is a common plant that grows in nitrogen-rich soils such as garbage, sidewalks and other weeds and undeveloped areas. A. vulgaris is a tall, herbaceous, perennial plant that grows 1-2 m (rarely 2.5 m) in height, with numerous rhizome systems. Instead of being dependent on seed propagation, it is propagated by plant expansion and anthropogenic propagation of rootstock fragments. The leaves are 5-20 cm long, dark green, pinnate and sessile, with dense, white hairy hairs underneath. The straight branches are grooved and usually have a reddish-purple tinge. The flowers are relatively small (5 mm long), rather symmetrical radial with numerous yellow or dark red petals. Narrow and numerous chapter (flower heads), all fertile, scattered in grape laths. It blooms from summer to early autumn. Many species of Lepidoptera (butterflies and moths), such as Ostrinia scapulalis, feed on the leaves and flowers of the plant.
