Taxonomy The plant was first described in 1836 by Augustin Pyramus de Candolle. (De Candolle used neuter endings for the specific epithets of Erigeron, but the word is masculine, being derived from the Ancient Greek word , geron, old man.) The specific epithet refers to Wilhelm Friedrich Karwinski von Karwin, who collected the plant in Mexico according to de Candolle.

Cultivation Erigeron karvinskianus is also cultivated for its daisy-like blooms, and is often confused with the closely related true daisy Bellis perennis. 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. It was used to colonise the concrete terraces of the football stadium (Estadio Azteca) built in Mexico City for the 1970 World Cup.
