Roadsides, fencerows, clearings, and shores. A species so long grown in various forms for its fruit that its precise origin in the Old World is obscure; it is often thought to have arisen as a hybrid. First collected in 1892 in St. Clair Co. European specimens seem often to lack the conspicuous glands on the teeth of the leaf that characterize ours.
