This species can form rather large vegetative stands and can be difficult to control. Not a good species for cultivation. Some authorities consider S. altissima L. (Tall Goldenrod) to be synonymous with S. canadensis. Solidago altissima has involucres more than 3 mm long, while S. canadensis has involucres less than 3 mm long.
