Erigeron quercifolius, commonly known as Oakleaf Fleabane, is a perennial herb native to open woodlands and savannas in the southeastern United States. It typically grows to a height of 1-3 feet (0.3-0.9 meters) and a width of 1-2 feet (0.3-0.6 meters). The plant features erect stems with toothed, oak-like leaves and clusters of small daisy-like flowers with white to pale lavender ray florets surrounding a yellow disc, blooming from late spring to early fall. The flowers are moderately showy and attract a variety of pollinators.

Oakleaf Fleabane is valued for its wildlife benefits, as it serves as a food plant for various Lepidoptera larvae. It is used in native plant gardens, borders, and as a ground cover, particularly in naturalized areas. This species thrives in full sun to part shade and prefers well-drained soils, though it is tolerant of a range of soil types. It is drought-tolerant once established and requires minimal maintenance, making it a suitable choice for xeriscaping. While generally disease-free, it can occasionally suffer from powdery mildew in humid conditions. Erigeron species are not known for aggressive roots or significant invasiveness, but some can self-seed prolifically if conditions are favorable.CC BY-SA 4.0
