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.

Native to Central and South America but like G. parviflora now a nearly cosmopolitan weed of temperate and subtropical areas. Thrives in populated areas: poorly kept lawns; along hedges, sidewalks, and gardens; roadsides and parks; and in greenhouses. First collected in Michigan in Ingham Co. (1892), but soon (1901) found in Detroit, Wayne Co.; widespread across southern Michigan and even in Gogebic Co. before 1920.
