Some American species have also been introduced into Europe and other parts of the world.

Its habitat includes tundra and mountain meadows.
Solidago houghtonii is a rare North American species of flowering plant in the family Asteraceae known as Houghton's goldenrod. It is native to southern Ontario, Canada and the northern United States. It is threatened by the loss and degradation of its habitat. It is a federally listed threatened species of the United States and it is designated a species of special concern by Canada's Committee on the Status of Endangered Wildlife in Canada.

Solidago puberula, the downy goldenrod, is a plant species native to eastern North America from Nova Scotia and Ontario south to Florida and Louisiana. Two subspecies are commonly recognized:
Solidago arguta, commonly called Atlantic goldenrod, cut-leaf goldenrod, and sharp-leaved goldenrod, is a species of flowering plant native to eastern and central North America. It grows along the Gulf and Atlantic states of the United States from Texas to Maine, inland as far as Ontario, Illinois, and Kansas. It is primarily found in areas of woodland openings, such as outcrops or clearings.
Solidago brachyphylla is a North American species of flowering plant in the family Asteraceae known by the common name Dixie goldenrod. It is native to the southeastern United States, from southern Mississippi to the Carolinas.
Solidago latissimifolia, common name Elliott's goldenrod, is North American species of flowering plants in the family Asteraceae. It is native to the Atlantic Coast of the United States and Canada, from Nova Scotia south to Alabama and Florida.
Solidago mollis is a North American species of flowering plant in the family Asteraceae known by the common names velvety goldenrod, soft goldenrod or Ashly goldenrod. It is native to the central United States and central Canada, primarily the Great Plains from the Canadian Prairie Provinces south as far as Texas and New Mexico.
Solidago radula, the western rough goldenrod, is a North American plant species in the family Asteraceae. It is found primarily in the southern Great Plains and the Mississippi Valley of the United States, with isolated populations farther east in Kentucky, Georgia, and the Carolinas.
Solidago sciaphilia is known as shadowy goldenrod or cliff goldenrod. The species is endemic to bluffs along the Mississippi River in southern Minnesota, and the driftless area of southwestern Wisconsin, northern Iowa and Illinois. Throughout its range, S. sciaphila is strongly associated with dolomite and sandstone bedrock, especially dry cliffs. It can be similar to Solidago speciosa but has more serrate lower and mid stem leaves and is generally smaller to much smaller when growing in pockets of shallow soil on cliffs. Small plants are similar to Solidago hispida in general appearance. Blooming occurs late August through late September; fruiting occurs throughout September. Shadowy Goldenrod is considered a Special Concern species in Wisconsin and Minnesota, and considered threatened in Illinois. This species can be significantly impacted by rock climbing activities.
Solidago ulmifolia, commonly known as elmleaf goldenrod, is a North American species of goldenrod in the family Asteraceae. It is found in Canada and the eastern and central United States.
Solidago sect. Ptarmicoidei is a section of flowering plants in the genus Solidago. They are sometimes considered a separate genus: Oligoneuron. Like related species they are known as goldenrods. This section contains seven species of perennial herbs, all native to North America. They are distinguished from other goldenrods by their corymbiform flowerheads, which are flat or rounded in profile and about as broad as tall or broader, for which they are sometimes called flat-topped goldenrods.
