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.

Lithospermum canescens (Michx.) Lehm.
Coefficient of Conservatism: 10
Coefficient of Wetness: 5
Wetness Index: UPL
Physiognomy: Nt P-Forb

Lithospermum canescens Ann Arbor Natural Area Preservation

Sandy prairie remnants; openings in oak and jack pine savanna; edges of forests, roads, and railroads.

The texture of the pubescence is sufficiently different from that of L. caroliniense to enable an experienced person to separate the two by merely “petting” the foliage; that of L. caroliniense is decidedly rough. The flower color tends to be deeper (more orange) in L. canescens. Both this species and L. caroliniense (as well as some others) have a pigment in their sap, especially in the sturdy taproot, which yields a strong purple-red dye.
