Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, michiganflora.net will point to this new site.

The new site offers several benefits over the existing website, including real coordinate mapping, giving a clearer view of the density of documentation as well as more precision about plant distributions and their link to landforms. We will also have the ability to update species pages more regularly, both in terms of new collections and as more existing Michigan specimens are georeferenced. In addition, we have a better photo display, and offer indented keys.

Hibiscus moscheutos L.
Common Name: SWAMP MALLOW, ROSE MALLOW
Coefficient of Conservatism: 7
Coefficient of Wetness: -5
Wetness Index: OBL
Physiognomy: Nt P-Forb

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.
