This is the common garden apple, a major fruit crop in Michigan (which stands third in the nation in apple production) and frequently spread to roadsides, shores, railroad grades, fields, disturbed places, and even forested areas. First collected in 1884 in Keweenaw Co.
Human beings discarding cores are doubtless a major agent of dispersal. Originally native in Eurasia, the domestic apple has been greatly modified and diversified by selection and also hybridization, so that the taxonomy is obscure. In fact, Korban & Skirvin (1984) argue that the name for the cultivated apple is M. ×domestica Borkh.
