Erigeron karvinskianus
An airy, sprawling perennial that mounds 10 to 20 inches tall and spreads 2 to 3 feet, producing a long, nearly year-round show of small white daisies that age to pink. It thrives in full sun to light shade with moderate water and reseeds readily to fill in over time. Tough and self-cleaning, it softens hard edges and spills gracefully over walls and slopes. Ideal for borders, between pavers and steps, rock gardens, parking strips, and cascading over retaining walls.
