|Ecology:||Old fields; roadsides; waste places|
|Blooming Period:||August to September|
|Typical Height Range:||3' to 5' (9 to 15 dm)|
|What to look for in the field:|
|The capitulescence consists of many crowded, ascending or spreading and often recurved branches. It is located at the top of the stem and is sometimes conical in shape. Branches are densely pubescent. Heads are numerous and crowded on branches, forming one-sided arrays.|
|Stems are glabrous (but not glaucous) below, becoming pubescent above, in the capitulescence. Galls due to insects are sometimes present in stems.|
|Basal and lower stem leaves are deciduous by flowering. Mid- to upper stem leaves are narrowly lanceolate, tapering to long points, have three main parallel veins, and lack petioles. Leaves are variously toothed and are pubescent mostly along veins beneath. Stem leaves become only gradually smaller upward.|
|Plants tend to form more/less compact colonies from rhizomatous growth.|
Note: Some scholars considered Solidago canadensis and Solidago altissima to be variations of the same species. The current thinking - in Flora of North America and elsewhere - is that though they are very closely related, they are not the same species. S. altissima is usually much taller, stouter and more pubescent than S. canadensis. Also, though both are colonial from rhizomes, the colonies of S. altissima are capable of becoming vastly larger than those of S. canadensis. The dense pubescence of S. altissima gives the foliage a slight gray-green color that is lacking in S. canadensis. Most texts are in agreement that the leaves of S. canadensis are more prominently toothed than those of S. altissima. However, I have seen some plants that have nearly untoothed leaves, but possess the characteristics of S. canadensis otherwise.
There are two variations of S. canadensis in New England: var canadensis and var hargeri. Var hargeri is distinguished primarily by the more dense stem pubescence, but otherwise is similar to var canadensis.
