Overview

Ceanothus gloriosus is Point Reyes ceanothus (Point Reyes creeper), a prostrate spreading evergreen shrub growing 6-18 inches (15-45 cm) tall and 4-8 feet (1.2-2.4 m) wide. Blue to violet-blue flowers in dense rounded clusters 1-2 inches (2.5-5 cm) at branch tips in March-April (4 weeks). Small glossy dark green leathery leaves 0.5-1 inch (1.3-2.5 cm) with spiny-toothed holly-like margins. In Rhamnaceae. Gloriosus = glorious. Endemic to coastal Marin County, California — Point Reyes National Seashore. One of the lowest-growing Ceanothus species — a prostrate ground-cover form. Nitrogen-fixing (actinorhizal with Frankia). Short-lived (8-15 years) — this limited lifespan is the primary limitation. Do not irrigate in summer once established — summer water promotes fatal root rot (Phytophthora). Sharp drainage required. Do not prune into old bare wood. The spiny-toothed holly-like margins distinguish C. gloriosus from smooth-leaved species. Hardy to about 15°F (-9°C). Drought-tolerant. Deer-resistant. Non-toxic. Zones 7-10. Full sun. Growth rate is moderate.

Native Range

Endemic to coastal Marin County, California — Point Reyes National Seashore and nearby headlands. Found on coastal bluffs, sandy flats, and open pine forests exposed to Pacific fog and wind.

Suggested Uses

Grown as an evergreen ground cover on slopes, coastal bluffs, and in Mediterranean-climate gardens, spaced 4-8 feet (1.2-2.4 m). Prostrate. Summer-dry. Sharp drainage. Native to Point Reyes. Non-toxic. Zones 7-10.

How to Identify

Identified by a prostrate evergreen ground-cover habit with dense blue flower clusters and small glossy dark green leaves with spiny-toothed (holly-like) margins. The prostrate habit and the holly-like leaf margins distinguish C. gloriosus from upright and smooth-leaved Ceanothus species. In Rhamnaceae.
