Erigeron argentatus, commonly known as Silver Fleabane, is an evergreen perennial herb native to the open woodlands, rocky slopes, and alpine regions of the Southwestern United States. It typically grows to a height of 10 to 40 centimeters (4–16 inches) and is adapted to high elevation habitats with well-drained soils. Silver Fleabane forms clumps with leaves and erect stems that are covered in dense white or silvery hairs, giving the plant its characteristic shimmering appearance. The stems culminate in single flower heads, each 1–2 centimeters (0.4–0.8 inches) wide, with blue or lavender ray florets surrounding a center of golden yellow disc florets. The flowering season extends through the summer months, and the flowers are modestly showy, attracting pollinators such as bees and butterflies.

Silver Fleabane is valued for its drought tolerance and its ability to thrive in poor, rocky soils, making it a suitable choice for rock gardens, xeriscaping, and naturalized areas. It is also used for its ornamental silver foliage and delicate flowers. In cultivation, it requires full sun to part shade, moderate water, and well-drained soils to mimic its native alpine conditions. While generally low-maintenance, it can be susceptible to root rot if overwatered or planted in poorly draining soils.CC BY-SA 4.0
