Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, 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.

Phacelia tanacetifolia Benth.
Coefficient of Conservatism: *
Coefficient of Wetness: 5
Wetness Index: UPL
Physiognomy: Ad A-Forb

This species, native from central California to northern Mexico, has occasionally been found as a waif beyond that range, presumably as an escape from cultivation, a contaminant in seed, or a hitchhiker on vehicles. The only Michigan collection was made in 1904 at the then recently established Upper Peninsula Experiment Station at Chatham, Alger Co. (L. M. Geisman, MSC); the railroad may have been associated with its introduction, or it may even have been cultivated. The leaves tend to be more finely pinnatifid than in the other two species, with the primary segments bearing at least small lobes or teeth.
