small-flowered blue-eyed Mary, collinsia
Note the opposite leaves in the middle of the plant, and whorled ones at the top. Flowers are clearly bilabiate (two-lipped) with blue lower lip. Hairiness along the stems is also evident in the photo.
Populations of C. parviflora often occur as masses of individual plants.
