About Solidago riddellii Frank
Solidago riddellii Frank, commonly called Riddell's goldenrod, is a perennial herb. It grows up to 100 cm (40 inches) tall, and has a branching underground caudex. A single plant system can produce up to ten stems. Its leaves are long and narrow, reaching up to 25 cm (10 inches) in length, and grow both along the stems and at the plant's base. One stem may sometimes produce as many as 450 small yellow flower heads; each flower head holds 7–9 ray florets that surround 6–10 disc florets. This goldenrod occurs in Manitoba and Ontario, Canada. In the United States, the core of its range lies in prairie regions of Minnesota, Iowa, southern Wisconsin, northern Illinois, northern Indiana, southern Michigan, and Ohio. Isolated populations have been reported in Georgia, Arkansas, and southwestern South Dakota. It grows in wet prairies and marshy areas.
