Ceanothus Blue Mound


Californian Lilac

Compact form smothered in blue flowers in early summer

This plant lives up to its name in early summer when smothered in bright blue flowers for weeks. Glossy, evergreen leaves are a feature for the rest of the year and this fast growing shrub makes a spreading mass of twiggy branches.


This beautiful plant will give of its best in full sun and well drained soil and a sheltered spot - away from cold winter winds.


Water frequently during dry weather until established.

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.
