Seaside Daisy

Erigeron glaucus

Description:

This wildflower is native to the coastline of Oregon and California where it grows on beaches, coastal bluffs and dunes. This is a perennial daisy reaching heights between 5 and 30 centimetres (2.0 and 11.8 in) 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 to 13 centimetres long. Its stems bear inflorescences of one to 15 flower heads which are variable in size from one to over three centimeters 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. While typical habitats include coastal bluffs, one highly specialised plant association is found within the two Cupressus macrocarpa dominant forests in Monterey County, California.

Habitat:

Not much naturalised on the south coast yet, but known to be weedy elsewhere. Highly tolerant of poor, dry soils and grows in a wide range of conditions. Has been recorded growing on tree fern trunks and old chimneys, so requirement for soil is minimal. A very popular garden plant which has great potential to spread into many types of native vegetation.

Notes:

Considered bush invader! Remove this plant from gardens which are close to native vegetation. Do not dump garden refuse. Pull small plants, or dig out larger ones: stems and rhizomes are woody and brittle and tend to break off. Scrape and paint or cut and paint woody stems. Will require follow-up.
