Erigeron karvinskianus

Santa Barbara Daisy, Mexican Daisy, Mexican Fleabane, Spanish Daisy, Seaside Daisy, Fleabane, Latin American Fleabane
Summary
Mexican fleabane, also called Santa Barbara daisy, is an evergreen perennial that forms a low, spreading mound with fine gray-green leaves. Daisylike flowers have white petals with a yellow center that opens and ages to pink, providing long bloom that can occur year‑round in mild climates; plants are typically 1–2 ft tall and 3–5 ft wide, with a trailing habit suited to rock walls, edges, and cracks.
It prefers full sun to partial shade and well-drained soil, is drought-tolerant once established, and can be propagated by seed, division, or cuttings. It self-seeds readily and can be invasive in mild climates; maintenance is low, with deadheading encouraged to extend bloom; common landscape uses include ground cover, edging, beds and borders, cascading over walls, rock gardens, containers, and hanging baskets; hardy in USDA zones 5–9.
