Solidago canadensis is widespread across all states in the US, growing in a variety of habitats, and is somewhat changeable in appearance. The solitary stems may reach a height of 4 feet and bear alternate leaves at intervals, their size increasing towards the base. They have coarse teeth at intervals along the edges. At the top is a dense, pyramidal cluster of small flower heads, each about 1/3 inch across; they consist of thin disc florets, surrounded by a ring of tiny ray florets. The disc florets are rounded when in bud, but open out to become tubular, and elongated, topped by a two-pronged style. Flowers are supported by green involucral bracts, numbering about 20.
