Erigeron karvinskianus is a species of flowering plant in the family Asteraceae known by the common names Mexican fleabane, Latin American fleabane, Santa Barbara daisy or Spanish daisy. This wildflower is native to much of South America and also Mexico, and is naturalized in many other places, including parts of Africa, Europe, New Zealand, and the west coast of the United States. This is a vigorous, spreading perennial plant growing from woody rhizomatous roots to a maximum height of 15cm. Its leaves are located along the stem, the basal leaves dying off as the plant bolts. They are sometimes slightly toothed or lobed near the tips. The inflorescences hold one or more flower heads which are each about 1 cm wide. They have golden yellow disc florets in the center and a fringe of up to 80 white to pinkish ray petals.
This plant is also cultivated for its daisy-like blooms, and is often confused with the closely related true daisy Bellis. It is frequently grown in crevices in walls or paving, where it rapidly spreads to provide a carpet of flowers. It has gained the Royal Horticultural Society's Award of Garden Merit.
Erigeron karvinskianus was first described in 1836 by Augustin Pyramus de Candolle. The specific epithet refers to Wilhelm Friedrich Karwinski von Karwin, who collected the plant in Mexico according to de Candolle.
