Tall goldenrod (Solidago altissima) is a robust wildflower that grows in open woodlands, prairies and in disturbed areas such as roadsides and fields. Its impressive display of golden flowers from late summer through fall attracts numerous pollinators, including butterflies, bees and beetles. Soldier beetles in the genus Chauliognathus are especially attracted to the nectar-rich blooms.
The plant’s green stems are pubescent, covered in fine white hairs. Leaves are alternately arranged, lanceolate and range from 3 to 6 inches long. Margins may be entire or shallowly toothed, and undersides are typically pubescent. The bright yellow flowering panicles can produce more than 1,000 small flowerheads in a large, conical array. Individual flowerheads are composed of numerous linear ray florets surrounding and average of three to six disk florets.
This species is also commonly referred to as Canada goldenrod, a name rooted in taxonomic confusion. Within the genus Solidago, S. altissima belongs to the subsection Triplinervae, along with S. canadensis. Some sources consider S. altissima to be a variety of S. canadensis, which in Florida is listed as Solidago canadensis var. scabra.
