Linaria vulgaris B. S. Walters

A Eurasian species, widely naturalized and sometimes cultivated. The oldest Michigan collection seen is by D. Cooley in 1844 (presumably from Macomb or Oakland Co.). Before 1890 it was known from Kent to Keweenaw Cos. Long a familiar and attractive weed along roadsides and railroads; on shores; thriving in fields, vacant lots, gravel pits, and dry disturbed ground generally.

The common name aptly refers to the yellow flowers with bright orange area on the lower lip. The linear leaves, mostly 1.5–4 (–5) mm wide, are often rather densely crowded.
