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.

Lamium amplexicaule L.
Common Name: HENBIT
Coefficient of Conservatism: *

A weed of lawns, flower beds, barnyards; around buildings, sidewalks, and railroads; fields and sandy or gravelly disturbed ground. First collected in Michigan in 1869 at Detroit (Wayne Co.).

The bright pink flowers are conspicuous, but are not always produced by plants in stressed, weedy situations; seeds apparently setting in these plants from cleistogamous flowers. 

This is a very cold tolerant plant, and will continue flowering well into November in sothern Michigan if frosts have not been too severe
