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.
Coefficient of Conservatism:
Coefficient of Wetness:
A Eurasian species, widely introduced in northern North America, collected in disturbed areas along a road in Gogebic Co. in 2004 by Ian Shackleford and Lynn Adams.
This is a weedy annual somewhat similar to Senecio sylvaticus in being quite pubescent and having tiny rays, but much more sticky-gandular and with dark tips to the involucral bracts and bracteoles, like S. vulgaris.
