How to identify Goldenrods (Solidago)

Goldenrods is characterized by its upright, sometimes slightly woody stems that support a wealth of simple, alternating leaves which can be either smooth or adorned with fine hairs. Typically, the leaf margins are entire to serrate. In the height of summer to early fall, the plant becomes a beacon of color, showcasing small, brilliant yellow blooms organized in tightly packed, wand-like clusters curving outward at the branch ends. The flowering tops span the stems, which can reach heights of 2 to 7 feet (60 to 210 cm), and through diligent deadheading, they can encourage further blooming.
