Chokeberry (Aronia) blossoms

The chokeberries, genus Aronia, are often mistakenly called chokecherries. This naming confusion is easy to understand considering there is a cultivar of the chokecherry Prunus virginiana 'Melanocarpa' and a species of chokeberry named Aronia melanocarpa. In fact, the two plants are not close relatives within their subfamily Spiraeoideae. Wikipedia
