How to identify this species: Identifying species of Solidago is not easy, but here goes... 1) leaves only 2-3 times as long as wide (Flora of Alberta) leaves of S. canadensis are longer for it we've measured a length-width ratio of 4 times as long as wide 2) Plants 1-4 dm tall  S. canadensis is a bigger plant, 4-12 dm high (Flora of Alberta) 3) Plants puberulent, S. canadensis is pubescent. 3) Leaves greyish-green 4) no basal leaves, plants rhizomatous, S. rigida has basal leaves and a branched caudex rather than rhizomes (Manual of Montana Vascular Plants) 5) S. mollis has a pyramidal inflorescence while S. rigida has a more flat-topped, corymbiform inflorescence.

When and where photographed: Took the above photos August 10th, prairie pasture amid wolf willow, Parklands, about 50 km east of our home in Regina, SK.
