Eriophyllum staechadifolium, commonly known as Seaside Woolly Sunflower, is a perennial herb native to coastal bluffs, dunes, and scrublands of Oregon and California, extending to the Channel Islands. It is well-adapted to sandy soils and tolerates salt spray, often found in the coastal strand plant community. This species typically varies in height from 1 to 5 feet, influenced by exposure to coastal winds and saline conditions. Its leaves are woolly, up to 2.8 inches long, and may be lobed or entire. From late spring to summer, it produces inflorescences with several flower heads, each showcasing golden yellow blooms with 30-40 disc florets surrounded by 6-10 small ray florets, which are particularly attractive to pollinators.

The Seaside Woolly Sunflower is valued for its drought tolerance and ability to thrive in poor, sandy soils, making it an excellent choice for coastal gardens and restoration projects. Its bright yellow flowers add a splash of color and are showy, attracting bees and butterflies. It is often used for erosion control on slopes and in xeriscaping. In cultivation, it requires minimal water once established, prefers well-drained soils, and thrives in full sun. While generally low-maintenance, it can be susceptible to root rot if overwatered or planted in poorly drained soils.CC BY-SA 4.0
