WaterFor California Lilac, during the growing season, water the plant thoroughly only when the surrounding soil begins to feel dry, roughly every 7 to 10 days, allowing the soil to dry slightly between waterings. Use approximately 1 to 2 gallons of water each time you water an established plant, ensuring it soaks into the soil to encourage deep root growth. In cooler seasons or when rainfall is sufficient, you can reduce watering frequency. Overwatering can lead to root rot; therefore, it's important to have well-draining soil.
LightCalifornia Lilac thrives in full sun conditions, requiring at least 6 hours of direct sunlight daily. The ideal spot for this plant would be in an area where it receives unfiltered, direct light for most of the day. However, in extremely hot climates, some afternoon shade may be beneficial to prevent scorching.
TemperatureCalifornia Lilac can tolerate a wide range of temperatures, from coastal to inland valleys, typically thriving between 25°F to 95°F. However, it prefers a more moderate range, with ideal temperatures between 50°F to 75°F. It is relatively frost hardy but may require protection if temperatures drop below the lower threshold.
PruningPrune California Lilac to maintain shape and remove any dead or damaged branches; this is best done immediately after the plant finishes blooming, usually in late spring or early summer. Pruning helps to stimulate new growth and enhance flowering for the following season. Avoid heavy pruning as this plant does not respond well to it; light to moderate trimming annually is adequate.
CleaningAs needed
SoilCalifornia lilac (Ceanothus 'Puget Blue') thrives in well-draining soil with a pH between 6.0 to 8.0. A mix of loam, sand, and a small amount of organic matter makes an ideal soil for this plant. Avoid heavy clays and waterlogged conditions.
RepottingCalifornia lilac rarely needs repotting as it prefers to be undisturbed. It's commonly planted directly in the ground, and potted specimens should only be repotted when absolutely necessary.
Humidity & MistingCalifornia lilac enjoys moderate humidity levels but is quite adaptable and can tolerate the dry air often found in natural, outdoor environments.
Suitable locationsIndoor
Ensure bright light, minimal water, and good air circulation.

Life cycleThe California lilac 'Puget Blue' begins its life cycle when a seed germinates, typically in the spring, after exposure to moisture and warm temperatures. The seedling emerges and, with adequate sunlight and well-drained soil, slowly grows into a young plant, developing a deep root system and foliage. As it matures over several years, it enters the vegetative stage, where it produces dense, dark green leaves and woody stems. Upon reaching the reproductive stage, 'Puget Blue' blooms profusely in the late spring to early summer, with clusters of vibrant blue flowers that attract pollinators. After pollination, the flowers produce seeds, which can be dispersed by wind, animals, or gravity to propagate new plants. The plant then enters a period of dormancy in the winter months, reducing its metabolic activities before the next growth cycle begins.
PropogationPropogation time
Spring-Early Summer
The most popular method to propagate California lilac 'Puget Blue' is through semi-hardwood cuttings. This technique is typically performed during the summer months when the plant's new growth has begun to mature but is not yet fully hardened. Cuttings should be about 4 to 6 inches (10 to 15 cm) long and taken from healthy, disease-free branches. The lower leaves are removed, and the cut end is dipped in a rooting hormone to encourage root development. Then, the cutting is placed in a well-draining soil mix, ensuring at least two nodes are buried where leaves were removed. The soil should be kept consistently moist, and the cutting should be placed in indirect light. Roots usually develop within a few weeks, after which the new plant can be gradually acclimated to outdoor conditions before planting in its final location.
