Ceanothus gloriosus 'Anchor Bay' (Anchor Bay Ceanothus) - A dense, low-spreading groundcover with slightly arching branches that grows up to 3 feet tall and 4-6 feet wide. The leathery, dark green, holly-like leaves are toothed along the margins and the small but numerous flower clusters are bright blue. 'Anchor Bay' is a garden-tolerant selection of the species that was singled out for its handsome foliage and slightly darker flowers.
Ceanothus gloriosus 'Anchor Bay' is one of the best groundcover ceanothus for coastal sites but also does well in inland conditions if given a bit of shade and modest irrigation during the summer months. Hardy to about 15 degrees F. Plants also tolerate salt spray and are less susceptible to deer browse than other ceanothus due to their spiny leaves.
This plant is a selection of Ceanothus gloriosus var. gloriosus, the Point Reyes Ceanothus or Glory Mat, which is endemic to coastal bluffs and dunes along the northern California coastline from Marin County north to Mendocino County. It was selected from a group of seedlings by the University of California at Davis Arboretum in the early 1970's from seed collected by Roman Gankin and Andrew Leiser at Anchor Bay in southern Mendocino County and was introduced into the nursery trade by the Saratoga Horticultural Foundation in 1976. We have grown this great plant since 1993.
The genus name comes from the Greek word keanthos which was used to describe a type of thistle and meaning a "thorny plant" or "spiny plant" and first used by Linnaeus in 1753 to describe New Jersey Tea, Ceanothus americanus. The specific epithet means "glorious" or "superb".
