Erigeron flagellaris, commonly known as Trailing Fleabane, is a perennial herb native to a variety of habitats including alpine regions, meadows, open woodlands, and rocky slopes across western North America. It typically grows up to 6 inches tall and spreads via stolons to form extensive mats, which can be useful for erosion control. Each stem usually produces a single flower head with white ray florets surrounding a center of yellow disc florets, blooming from late spring to early summer. The flowers are modest in size but can be quite numerous, creating a carpet of color.

Trailing Fleabane is valued for its ability to adapt to various garden settings, requiring minimal maintenance once established. It is often used in rock gardens, as a ground cover, or in borders where its trailing habit and profuse flowering can be appreciated. This plant prefers well-drained soils, tolerates a range of soil types, and can thrive in full sun to part shade. While it is drought-tolerant once established, regular watering will encourage more vigorous growth and flowering. There are no major disease or pest issues, but it can spread aggressively if conditions are ideal.CC BY-SA 4.0
