Collinsia sparsiflora occurs in open habitats and woodland edges; it is easily recognized by the red blotches on fruits and the frequent occurrence of a single flower per node. In immature plants, the presence of a red band spanning the circumference of the base of the calyx lobes along with the relatively frequent occurrence of a single flower per node distinguishes C. sparsiflora.
V. M. Newsom (1929) recognized five varieties in Collinsia sparsiflora.
Two varieties are recognized here to accommodate the general pattern of locally distinct small- and large-flowered populations of Collinsia sparsiflora. Where these taxa are sympatric, the author has not found intermediates that suggest local interbreeding.
