Disturbed ground, ditch banks, and abandoned fields; not really established anywhere out of cultivation, but treated here because it is regularly introduced. The potato’s ancestors were originally native in highlands of South America, but our well-known vegetable was developed in cultivation over thousands of years.
Surviving, where dumped, long enough to flower or occasionally for as long as 5 years in abandoned fields; First collected in 1892 in St. Clair Co., but doubtless the humble potato is more common as a waif than the few collections suggest.
