Erigeron glaucus is a species of flowering plant in the family Asteraceae known by the common name seaside fleabane, beach aster, or seaside daisy. It is native to the West Coast of the United States.
E. glaucus is a perennial daisy reaching heights between 5 and 40 centimetres (2 and 15+1⁄2 inches) with branching, nodding stems which may be glandular and hairy [2] 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 2–13 cm (3⁄4–5 in) long. [3] From April to August, its stems bear inflorescences of 1–15 flower heads which vary in size from about 1 to 6.5 cm (1⁄2 to 2+1⁄2 in) wide. [2] The centers contain golden yellow disc florets and the edges are fringed with about 100 ray florets which may be long or quite short, and are shades of deep blue and purple to nearly white. [4] [5] The fruit is seed-like with many bristles at the tip. [2]
Unusual for its genus (but not for plants near the coast), the plant is somewhat succulent. [2]
The wildflower is native to the coastline of Oregon and California where it grows on beaches, coastal bluffs and dunes. While typical habitats include coastal bluffs, one highly specialised plant association is found within the two Cupressus macrocarpa dominant forests in Monterey County, California. [4] [5]
E. glaucus occurs in several different plant associations. One of the specialized habitats is within the Monterey cypress forests of the Central California coast. [6]
Hesperocyparis macrocarpa is a coniferous tree. It is commonly known as the Monterey cypress and is one of several species of cypress trees endemic to California. In New Zealand, where it is also widespread, it is simply known as "macrocarpa".
Erigeron is a large genus of plants in the family Asteraceae. It is closely related to the genus Aster and the true daisies in the genus Bellis. The genus has a cosmopolitan distribution in dry, mountainous areas and grassland, with the highest diversity in North America.
Cupressus goveniana, now reclassified as Hesperocyparis goveniana, with the common names Californian cypress and Gowen cypress, is a species of cypress, that is endemic to California.
Erigeron concinnus, the Navajo fleabane, tidy fleabane or hairy daisy, is a perennial flowering plant in the family Asteraceae.
Erigeron annuus, the annual fleabane, daisy fleabane, or eastern daisy fleabane, is a species of herbaceous, annual or biennial flowering plant in the family Asteraceae.
Erigeron aphanactis is a species of flowering plant in the family Asteraceae known by the common name rayless daisy, or rayless shaggy fleabane. This wildflower is native to the western United States, primarily the Great Basin and Colorado Plateau regions.
Erigeron cervinus is a North American species of flowering plant in the family Asteraceae known by the common names Siskiyou fleabane and Siskiyou daisy.
Erigeron eatonii is a North American species of flowering plants in the family Asteraceae known by the common name Eaton's fleabane.
Erigeron foliosus, known by the common names leafy daisy and leafy fleabane, is a North American species of flowering plants in the family Asteraceae.
Erigeron karvinskianus, the Mexican fleabane, is a species of daisy-like flowering plant in the family Asteraceae, native to Mexico and parts of Central America.
Erigeron parishii is a species of flowering plant in the family Asteraceae known by the common name Parish's fleabane.
Erigeron strigosus is a species of flowering plant in the family Asteraceae known by the common names prairie fleabane, common eastern fleabane, and daisy fleabane.
Erigeron utahensis is a North American species of flowering plant in the family Asteraceae known by the common name Utah fleabane.
Erigeron biolettii is a species of flowering plant in the family Asteraceae known by the common names streamside daisy and Bioletti's fleabane. It was named for University of California Professor of Viticulture and Enology Frederick Bioletti when he was an undergraduate. It is endemic to California, where it is known only from the North Coast Ranges from Marin and Solano Counties north to Humboldt County. There is a report of the species growing in Alameda County, but it is from an urban area in Crestmont, hence probably either a cultivated specimen or an escaped introduction.
Erigeron petrophilus is a species of flowering plant in the family Asteraceae known by the common names rockloving erigeron or cliff fleabane. It is native to the mountain ranges of California from Siskiyou County south as far as San Luis Obispo County and El Dorado County. It also grows in southwestern Oregon.
Erigeron reductus is a species of flowering plant in the family Asteraceae known by the common name lesser California rayless fleabane. It is endemic to California, from Trinity County south as far as Alameda County and El Dorado County.
Erigeron sanctarum is an uncommon species of flowering plant in the family Asteraceae known by the common names saints fleabane and saints daisy. It is endemic to California, where it is known from San Luis Obispo and Santa Barbara Counties including two of the Channel Islands.
Erigeron supplex is a rare species of flowering plant in the family Asteraceae known by the common names supple daisy or supple fleabane. It grows along the coastline and in the Coast Ranges in California, north of San Francisco Bay. It probably remains only in Sonoma and Marin Counties. There is a report of it growing well inland in Shasta County, but this is from a farm and probably a cultivated specimen.
Erigeron serpentinus is a rare species of flowering plant in the family Asteraceae known by the common names serpentine fleabane and serpentine daisy. It is endemic to Sonoma County, California, where it is known from three occurrences in and around The Cedars, in the Coast Ranges east of Salt Point and west of Healdsburg. There are an estimated 1100 individuals in existence. The Cedars is a canyon habitat with serpentine soils surrounded by non-serpentine terrain; it is home to several rare serpentine-endemic plant species. This daisy was discovered there and described to science in 1992.
