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.

Calcareous sandy or gravelly shores, including interdunal flats and conifer thickets; river and stream banks, swamps (especially cedar), occasionally fens; marshy ground, meadows, springy and marly places, crevices and shallow soil at limestone outcrops; moist jack pine and oak scrub. Especially conspicuous in the straits region.

In f. lutescens Farw., the calyx and bracts are bright yellow rather than red; it is found occasionally, usually with the common form but sometimes in a stand by itself. Forma alba Farw. was described as white, and orange color foms have also been seen.
