SWAMP MALLOW, ROSE MALLOW
Marshes, open river bottoms, and often adjacent disturbed ground. The species is more common in salt marshes of the Atlantic coast, but is locally frequent in southern Michigan and other inland sites.
Populations in marshes near Lakes Erie and Michigan are certainly native; some inland records in drier habitats, in weedy sites along roads, and also more northern colonies, are doubtless escapes from cultivation. Escapes from cultivated plants may have a wide range of flower color, not simply pinkish as in wild plants, and tend to be more compact.
