Davidson's blue-eyed Mary (Collinsia bartsiifolia var. davidsonii) is a flowering plant in the plantain family (Plantaginaceae), endemic to California. This variety of Collinsia bartsiifolia, commonly known as white blue-eyed Mary, is found in drier regions east of the South Coast and Transverse ranges, where it grows in open, sandy places. It is a small, drought-tolerant annual wildflower that blooms in spring with pea-shaped flowers that range in color from white to lavender to purple.

The plant produces a slender, hairy stem lined with a few thick, narrowly oblong leaves with slightly rolled-under edges. Its inflorescence is a loose series of flower whorls, with each flower displaying pouched and folded petals, two toothed upper lobes, and three notched lower lobes.

Like other blue-eyed Marys, Collinsia bartsiifolia var. davidsonii may attract native bees, butterflies, moths, and even birds during bloom.
