Expert tips
The key tip
Ceanothus gloriosus thrives in very well-drained soil, even poor soil. Plant it on a slope or mound: standing winter water can weaken this coastal plant.
The common mistake
Watering it like a 'normal' plant or planting it in a wet low-lying area: it rots in autumn-winter despite its hardiness.
The pro's trick
Pinch back young stems lightly in June to naturally densify its shape: a Ceanothus gloriosus left to grow freely becomes too open and loses its beauty.
Care
Exposure
Plant your creeping ceanothus in full sun to get generous, dense flowering. A minimum of 6 hours of direct sunlight per day is recommended. In very hot climates, some afternoon shade can be beneficial.
Watering
Water regularly during the first year to establish the root system, then gradually reduce. Once established, creeping ceanothus tolerates drought well. Water moderately in summer and very little in winter. Avoid stagnant water which can cause root rot.
Soil
Prepare well-drained, light soil that's rather poor in organic matter. This plant prefers slightly acidic soils. Improve drainage with sand or gravel if your soil is heavy. Nutrient-rich soil encourages vegetative growth at the expense of flowering.
Pruning
Prune lightly after flowering (June-July) to maintain shape and encourage branching. Remove dead or damaged stems as soon as you spot them. Avoid severe pruning which could weaken the plant.
Fertilizing
Creeping ceanothus needs only minimal fertilizer. A light application of balanced fertilizer in spring is more than enough. Excessive fertilizing stimulates foliage growth at the expense of flowering.
Diseases and pests
This plant is generally robust and rarely affected by diseases if drainage conditions are respected. Watch for root rot in case of excess moisture. Aphids can occasionally appear: treat with soapy water if necessary.
Did you know?
Creeping ceanothus is a California native shrub that was historically used by indigenous peoples for various traditional applications. Its Latin name 'gloriosus' reflects its magnificent blue-violet flowering that illuminates California's rocky slopes. It's an ideal pioneer plant for stabilizing slopes and creating spectacular floral carpets in Mediterranean or dry gardens.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
