I am worried that I have tagged all of the Canadian Serviceberry photos as pin cherry. I have to inspect hundreds of photos now. The flowers are very similar. The serviceberry, which John is very familiar with, is everywhere now. If the birds haven't eaten them. We have one brush of it that was stripped in twenty-four hours by birds. This shrub is also called juneberry, shadblow, shadblow serviceberry, shadbush, shadbush serviceberry, sugarplum, thicket serviceberry, currant tree, and, my favorite, chuckleberry.
