WaterThe California Lilac should be watered moderately, especially during dry spells. In the growing season, water the plant once every week with approximately 1 to 2 gallons, ensuring the soil is moist but not waterlogged. During the winter months when the plant is dormant, reduce watering frequency, providing just enough water to prevent the soil from drying out completely, which may be once every 2 to 4 weeks. Be cautious of overwatering as this can lead to root rot.
LightCalifornia Lilac thrives best in full sun, receiving at least 6 to 8 hours of direct sunlight daily. Plant it in a location that ensures plenty of sunlight for healthy growth and optimal flowering. Avoid heavily shaded areas which can hinder its growth and reduce flowering.
TemperatureCalifornia Lilac prefers a temperate climate and can tolerate a range of temperatures. It can survive brief periods of cold down to about 10 degrees Fahrenheit, but ideally, it should be kept in areas where the temperature remains above 20 degrees Fahrenheit. The ideal temperature range for maximum growth and blooming is between 50 and 75 degrees Fahrenheit.
PruningPrune California Lilac to maintain its shape and promote healthier, more robust growth. It's best to prune after the plant has finished blooming in late spring or early summer. Pruning too often or too late in the year can reduce the number of flowers, as it blooms on old wood. Remove any dead or crossed branches and shape the plant as desired.
CleaningAs needed
SoilThe Carmel Creeper (common name) thrives in well-draining soil with a pH range from 5.5 to 7.5. An optimal soil mix might include equal parts loam, sand, and compost to facilitate drainage and fertility. Adjust pH with lime if too acidic or sulfur if too alkaline.
RepottingCarmel Creeper does not require frequent repotting; it can typically be repotted every 2-3 years, or as needed when it outgrows its current container.
Humidity & MistingCarmel Creeper prefers moderate humidity levels, although it is quite adaptable and can tolerate both coastal conditions and drier inland climates.
Suitable locationsIndoor

Life cycleThe Carmel creeper begins life as a seed that, upon germinating, develops a root system and a small shoot that emerges from the soil. It quickly grows into a young plant with distinctive leaves, and as it matures, it forms a dense groundcover with horizontal branching. During the spring to early summer, it enters its reproductive stage, blooming with clusters of small, blue to violet flowers that attract pollinators. After pollination, the flowers develop into small seed capsules, which, when mature, release seeds to propagate the next generation. Throughout the growing season, it requires adequate sunlight, water, and well-drained soil to thrive. Carmel creeper has an evergreen habit, but in colder climates or under stress, it may partially shed leaves before entering a dormant phase during the winter, conserving resources until conditions improve for new growth in the spring.
PropogationPropogation time
Spring to Summer
The most popular method of propagating Ceanothus griseus var. horizontalis 'Silver Surprise', commonly known as the Carmel Creeper, is through semi-hardwood cuttings. This is typically done in late summer to early autumn. Cuttings should be taken from the current year's growth that has partially matured; the wood should be somewhat firm but still flexible. It's important to remove the lower leaves and possibly dip the cutting base in a rooting hormone for better results. The cuttings should then be placed in a well-draining potting mix, kept moist, and ideally placed in a location with indirect sunlight and a consistent temperature until roots develop. This can take several weeks to a few months depending on conditions.
