Solidago gigantea is a North American plant species in the sunflower family.[3] Its common names include tall goldenrod[4] and giant goldenrod,[5] among others. It is a widespread species known from most of non-arctic North America east of the Rocky Mountains. It has been reported from every state and province from Alberta to Nova Scotia to Florida to Texas, and also from the state of Nuevo León in northeastern Mexico.[6][7]

Solidago gigantea is a herb up to 200 cm (80 inches) tall, sometimes spreading by means of underground rhizomes. They often grow in clumps, with no leaves at the base but numerous leaves on the stem. At the top, each stem produces a sizable array of many small flower heads, sometimes several hundred. Each head is yellow, containing both disc florets and ray florets.[4]

Solidago gigantea is found in a wide variety of natural habitats, although it is restricted to areas with at least seasonally moist soils.[4][8]

Solidago gigantea is the state flower of Kentucky and Nebraska.[9]
