Erigeron glaucus 'Cape Sebastian' (Cape Sebastian Seaside Daisy) - This low growing form of seaside daisy is only 3 to 4 inches tall and spreads to 18 to 24 inches wide. The 1 inch wide lavender daisy blooms, with yellow centers, cover the plant profusely in the spring through summer with sporadic flowering througout the year. Plant in a location that receives full sun to light shade along the coast or light shade in warmer inland locations. Fairly drought tolerant but looks more robust with occasional irrigation. It is hardy to at least 10 F. Tolerates coastal conditions and heavy clay soil. Trim off old flowers and when plants get lanky, cut back to 1 to 2 inches of stem in late fall. This is the smallest and tightest growing of the Erigeron glaucus selections. Seaside daisy is native along coastal bluffs, dunes and beaches below 500 feet in the coast shrub community from the Channel Islands and mainland Santa Barbara County north to Oregon with this selection coming from near Cape Sebastian State Park, south of Gold Beach Oregon, where it was selected by Brett Hall, the UC Santa Cruz Arboretum Manager. As noted in Carol Bornstein, Dave Fross and Bart O'Brien's California Native Plants for the Garden "Seaside daisy performs best in coastal gardens and works well in mixed borders, meadows, or containers. In richer soils it looks better and blooms more profusely than it will in sandy or rocky soils. In inland gardens plants in full sun flower spectacularly throughout spring but often burn to a crisp during summer … individual seaside daisy plants have a useful garden life span of two to seven years." The name for the genus comes from the Greek words 'eri' meaning early or perhaps 'erio' meaning wooly and 'geron' meaning "old man" which alludes to the bristly or wooly seed heads. The specific epithet is the Latin word (from the Green 'glaukos') meaning silvery" or "bluish-green".
This information about Erigeron glaucus 'Cape Sebastian' displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
