Discussion

Some occurrences of Sida hermaphrodita may be the result of escapes from cultivation. It is generally rare except locally common along the Kanawha and Ohio rivers in Ohio and West Virginia (D. M. Spooner et al. 1985); it has been extirpated from Tennessee. Reports from Massachusetts, New Jersey, and New York refer to garden escapes. The species may or may not be native in Michigan.
