Erigeron annuus is an annual or biennial herbaceous plant with simple, alternate leaves and sparsely hairy green stems. It grows up to 5 feet (1.5 m) tall. Leaves are numerous and large relative to other species of Erigeron, with lower leaves, especially basal leaves, coarsely toothed or cleft. Upper leaves are sometimes toothed but may have a few coarse teeth towards the outer tips. Flower heads are white with yellow centers, with white to pale lavender rays. They appear from spring through fall.
It is grown as an annual plant, so it has no USDA hardiness zone.
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 works well in rock gardens, borders, flower beds, containers, and slopes. Seaside Daisy is highly attractive to butterflies, and the colorful visitors love the long growing season.
Seaside Daisy's care is not complicated, but it is 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 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.
