Erigeron glaucus is a perennial plant up to 12 inches (30 cm) tall, with branching, nodding stems which may be glandular and hairy to hairless. It grows from a stout rhizome and produces thick, firm, rounded to spoon-shaped leaves, sometimes with a few teeth along the edges, each two up to 5.2 inches (13 cm) long. Its stems bear inflorescences of one to 15 flower heads which are variable in size from 0.4 to 1.2 inches (1 to 3 cm) wide. The centers contain golden yellow disc florets and the edges are fringed with ray florets which may be long or quite short, and are shades of deep blue and purple to nearly white.

How to Grow and Care
Growing Seaside Daisies prefer well-draining soil and full sun, but the plants will tolerate light shade, especially in hot climates. The plant is well suited for xeriscaping, and also works well in rock gardens, borders, flower beds, in containers and on slopes. Seaside Daisy is highly attractive to butterflies and the colorful visitors love the long growing season.
Seaside Daisy care isn’t complicated, but it’s important to locate Seaside Daisy where the plants are protected from afternoon sunlight, as the intense heat will scorch the plant. Otherwise, just water the plant about once a week during dry weather. A 3-inch (7.5 cm) layer of mulch keeps the soil cool and moist.
Deadhead wilted blooms regularly to encourage continued blooming and to keep the plant tidy. Trim the plant down if it looks leggy in late summer. You’ll be rewarded with a rejuvenated plant and another flush of colorful blooms… – See more at: How to Grow and Care for Seaside Daisy (Erigeron glaucus)
