Collinsia concolor grows in dry habitats of the Peninsular Ranges. Flowers in tiers of dense whorls with bluish-tinged (or blue-blotched) corollas, a triangular region of purple spots in the adaxial lip, and lack of curved appendages at the bases of the filaments are unique to it. It is frequently confused with C. heterophylla because of morphological similarity and range overlap.
