Seaside Daisy Plant Sets

Seaside Daisy (Erigeron glaucus), also known as Beach Fleabane or Seaside Fleabane, is a cheerful, low-growing native perennial that brings vibrant beauty to the Pacific coast. Blanketing itself in lavender-purple flowers with golden centers from spring through late summer, it is native to the bluffs, dunes, and rocky slopes of California and Oregon. Its thick, bluish-green glaucous leaves are perfectly adapted to withstand salt spray, coastal winds, and dry summers. Spreading steadily by rhizomes to form a dense, flowering mat, it is an outstanding low-water groundcover for sunny coastal gardens where other plants might struggle. Key Features: Prolific Season-Long Bloom: Lavender-purple daisy flowers appear from April through August, providing flushes of new blooms and months of rich garden color. Coastal Tough: Native to exposed bluffs and dunes, this perennial thrives in salt spray, coastal wind, and sandy soils where few plants can compete. Low Groundcover: Spreading rhizomes fill in along garden edges and sunny slopes with a dense, weed-suppressing mat just 6–12 inches tall. Pollinator-Friendly: Abundant flowers attract native bees, small butterflies, and beneficial insects throughout the long bloom season. Natural Habitat Look: The blue-green foliage and lavender flowers beautifully evoke the natural California and Oregon coastlines, making it ideal for naturalistic coastal plantings. Eco-Friendly: Grown non-GMO and neonicotinoid-free to ensure a healthy ecosystem for your local wildlife. Our plants ship in 3-inch pots, have a developed root mass, and emerging foliage around 2-5 inches high. Why Choose Seaside Daisy? Seaside Daisy pairs lasting garden beauty with real ecological benefit. This low, mat-forming perennial spreads effortlessly by rhizomes to create a 12 to 24 inch wide canopy of resilient blue-green foliage. The continuous flushes of cheerful daisy flowers offer a critical nectar source for native bees and small butterflies, while the dense groundcover supports ground-dwelling insects. It is a rugged, low-maintenance choice that handles harsh coastal conditions with ease, supporting local biodiversity season after season without demanding extensive care. Planting Tips: Location: Plant in full sun to part shade. It requires well-drained sandy, loamy, or rocky soils. It easily tolerates poor fertility, coastal fog, and salt spray but will not survive in prolonged wet conditions or heavy clay. Watering: Water regularly during the first growing season to establish roots. Once established, it tolerates occasional dry spells. Maintenance: Minimal care required. There's no need to deadhead the flowers, as allowing them to go to seed provides a valuable food source for birds. Leaving the stems standing in the fall offers overwintering sites for beneficial insects. If desired, cut back the stems in late spring after pollinators have emerged.
