Stout goldenrods are natives of North America. For a comparison chart of some of the varieties of goldenrods, see Solidago.

Identification: Stems are stiffly erect, 18-60" (45-152 cm) high, often red. Leaves are egg-shaped, and toothed. They usually form a rosette of large leaves at the base. Leaves along the upper stem are small and narrow. Flowers form long clusters at the top of each stem. Individual flowers are closely attached to the stem, with 10-16 rays each. At the base of each flower are green back-curved tiny leaflets (bracts), a key identifying feature.

Edibility: Not edible.
