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, potentially becoming invasive in some areas.CC BY-SA 4.0
