A medium-sized tree introduced from Eurasia and once commonly cultivated; now escaped to roadsides, railroad corridors, along rivers, and in fields and thickets. Many specimens are clearly from cultivated trees or contain scant details about their provenance. The first specimen from a definitively wild tree was collected in 1956. This species is more widespread than the map indicates, being quite common along highways in the southeasternmost counties and in the Fox Valley. However, accessing these areas is usually impossible, which has most likely led to it being under-collected.
