Ceanothus griseus horizontalis Diamond Heights

Californian Lilac

Unique groundcover form with light coloured leaves

This Californian Lilac is aptly named. The pale yellow leaves have a deep green central splash and this plant will sparkle when grown in part shade where it is happiest to prevent the leaves being sunburnt. The evergreen leaves will light up a dull corner and are the perfect backing to the pale blue flowers that smother the ground covering branches in early summer.


Low growing, spreading and just the thing to cover a steep bank or at the front of a border in part shade and well drained soil.


Water the plant frequently in dry weather until established. Shelter from cold, winter winds.

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.
