Erigeron glaucus ‘Cape Sebastian’ (CA Native)
Erigeron glaucus ‘Cape Sebastian,’ also known as Seaside Daisy is a charming evergreen perennial. Of the Erigeron glaucus selections, ‘Cape Sebastian’ is the lowest growing and tightest growing.
In the spring and summer, it produces many lavender-periwinkle daisies with a yellow center. It has blue green, spoon-shaped foliage all year long. It can grow 3-4”H x 2’W. It is native to the California and Oregon coasts and can often be found growing along coastal bluffs, dunes, and beaches. These coastal dwellers have sturdy roots and can withstand windblown climates and cliffsides.
On the coast, they’ll thrive in full sun to light shade. If planted more inland, they’ll benefit from some afternoon shade. Like most natives, they require low water. E. glaucus tolerates sandy or clay soil and is cold hardy to 12°F. They’re an easy to care for plant that only needs light pruning once the flowers begin to fade. In late fall, trim off old flowers to help them keep their compact form and encourage more flowers. If the plants get too lanky, you can cut back to 1 to 2 inches of stem.
This low and spreading variety makes them a great groundcover. They perform best in coastal gardens and work well in mixed borders or containers. Plant them amongst other coastal natives like dudleya and California sea pink.
E. glaucus is a hardy drought tolerant plant that won’t be bothered by deer or gophers. They’re a reliable food source for bees and butterflies, so you can count on frequent visits from local pollinators. If the flowers are left to seed, song birds will also enjoy the feast!
The Sunset Western Garden Zones are 4-6, 15-17, 22-24.
