Amelanchier canadensis
[Shadblow Serviceberry]

Amelanchier canadensis, the Shadblow Serviceberry, tends to be confused with Amelanchier arborea, the Downy Serviceberry, and Amelanchier laevis, the Allegheny Serviceberry. However, A. canadensis, compared to A. arborea and A. laevis, is generally much more shrub-like (often forming thickets), flowers a week later, and produces upright flower clusters (as opposed to the pendulous racemes of A. arborea and A. laevis). The Shadblow Serviceberry is excellent for woodland plantings, naturalizing, and along stream and pond banks.…
