Solidago nemoralis, old field goldenrod

Euthamia graminifolia, grass-leaved goldenrod

Field of goldenrod in the Midwest.

Goldenrod is a common name for many species of flowering plants in the sunflower family, Asteraceae, commonly in reference to the genus Solidago.

Several genera, such as Euthamia, were formerly included in a broader concept of the genus Solidago. Some authors treat Oligoneuron, the flat-topped goldenrods, as a separate genus than Solidago,^[1] while others consider it a section: Solidago sect. Ptarmicoidei.^[2]

Goldenrods can be used as a sustainable method to enrich soil with nitrogen. With an increase of nitrogen levels, there can then be an increase of vegetative growth.^[3]

Plants known as goldenrods include:

• Bigelowia spp., rayless goldenrods, 2 species native to the Southeastern United States^[4][1]
• Cuniculotinus gramineus, Panamint rock goldenrod
• Euthamia spp., flat-topped goldenrods or grass-leaved goldenrods, 5 species native to North America^[1][5]
• Gundlachia triantha, Trans-Pecos desert goldenrod
• Lorandersonia microcephala, small-headed heath goldenrod
• Medranoa palmeri, Texas desert goldenrod
• Petradoria pumila, rock goldenrod
• Solidago spp., goldenrods, around 120 species native to the Americas, northern Africa, Europe, Asia^[6]
