Ceanothus thyrsiflorus Skylark


California Lilac

Compact form flowering from May to June

A compact, medium sized variety that looks great all year round thanks to its dark evergreen foliage and clusters of blue flowers in May and June.


Likes to bask in the sun, preferably in a sheltered location and works well as part of a mixed border or against a wall.


Grows well in almost any well drained soils, it is largely easy to grown as long as it is sheltered from cold winds and lightly pruned after flowering.

Native to North America, Californian Lilacs tend to be drought resistant and suitable for coastal locations.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
