1.Fleabane Glaucus — Overview
Erigeron glaucus, commonly known as Fleabane Glaucus or Seaside Daisy, is an enchanting coastal perennial belonging to the extensive Asteraceae family. This resilient species is indigenous to the rugged coastlines of western North America, thriving in challenging environments. It features a compact, mounding habit, typically reaching 6 to 12 inches in height, adorned with striking blue-green, somewhat glaucous foliage.
Its aesthetic appeal is further enhanced by a profusion of lavender-blue, daisy-like flowers, each with a bright yellow center disk. These captivating blooms emerge from late spring and continue through the summer, providing a vibrant display.
Highly adaptable, Fleabane Glaucus thrives in harsh conditions such as direct salt spray, prolonged drought periods, and nutrient-poor, quick-draining soils. This makes it an excellent choice for:
• Xeriscaping
• Rock gardens
• Seaside landscapes
Beyond its ornamental value, Erigeron glaucus is a significant pollinator attractor, drawing in various native bees, butterflies, and moths crucial for ecosystem health.
The genus name 'Erigeron' is derived from Greek, meaning 'early' and 'old man.' This refers to its early blooming and the fuzzy white seed heads that resemble an old man's beard, often appearing while new flowers are still forming. Historically, the common name 'fleabane' is thought to have originated from a traditional belief that the dried plants could repel fleas and other insects, a property attributed to its volatile compounds.
