Ceanothus - California lilac, wild lilac, or soap bush - is a genus of about 50–60 species of shrubs or small trees in the family Rhamnaceae, endemic to North America and especially California.
Most of the species are evergreen, some deciduous, 0.5–3 metres (1.6–9.8 ft) tall shrubs - with the exception of C. arboreus and C. thyrsiflorus, which are small multi-trunked trees up to 6–7 metres (20–23 ft) tall - with opposite or alternate (depending on species), 1–5 cm long leaves with serrated margins and blue, dark purple-blue, pale purple, white, greenish–white, or pink flowers produced in large, dense clusters.

Plant my california lilac
Plant between October and the end of March but not during frost periods. Check that the desired location meets the requirements described in the description, and avoid working in soggy soil. Dig a hole two to three times as wide as the root ball of your tree. Handle the root ball carefully to keep it intact while you place it in the hole. Put your shrub to the correct height, and replace the soil, respecting the order of the layers of possible - bottom layer to top. Tamp regularly. After planting, pour two watering cans at the bottom, then place a good layer of mulch.
Water my california lilac
Water regulary in the first weeks. Try to avoid watering on sunny afternoons to minimize the amount of moisture lost to evaporation. If your plant is in a pot, check the top soil in the pot either by looking at it or touching it with your finger. In any case, if it hasn’t rained in a month, water !
Prune my california lilac
Prune each year right after flowering, shortening the stems and cutting the withered flowers.
