Title: Would mountain ash (Sorbus sp.) grow in Michigan?
Answered by: Nan Hampton
Sorbus americana (American mountain ash) and its distribution includes Michigan. Here are more photos.
Sorbus decora (northern mountain ash) and its distribution includes Michigan. Here are photos.
Sorbus dumosa (Arizona mountain ash) and its distribution does NOT include Michigan.
Sorbus groenlandica (Greenland mountain ash) and its distribution does NOT include Michigan. Here is a photo.
Sorbus scopulina (Greene's mountain ash) and its distribution does NOT include Michigan. Here are photos.
Sorbus sitchensis (western mountain ash) and its distribution does NOT include Michigan. Here are photos.
So, Mr. Smarty Plants says "definitely yes" for the first two—S. americana and S. decora—but unlikely for the other 4 species.
