As its common name implies, Seaside Daisy (Erigeron glaucus) is a perennial plant in the Daisy family that grows on the coastline of California and also north into coastal Oregon. This cheerful plant has a long flowering season, which can be prolonged by deadheading spent flowers. It blooms profusely in shades of lavender and pink, with large yellow centers. The flowers are attractive to butterflies and bees.

Seaside Daisy is a sturdy, low-growing plant. It has very low water needs, especially when planted in coastal areas, where no irrigation is needed once it is established. When planted inland or in containers, some supplemental water is beneficial. Plant in sunny areas as a groundcover or part of a pollinator garden where it has room to spread.

Several cultivars are available. Wayne Roderick introduced two of the most common: Erigeron 'Wayne Roderick' and Erigeron 'W.R.' The 'Wayne Roderick' cultivar has dark purple flowers,and 'W.R.' is more heat tolerant, making it a good choice for inland gardens.
