Ceanothus ‘Ray Hartman’, commonly known as California Lilac, is a fast growing, evergreen shrub or small tree that brings bold color and strong structure into the landscape. It’s a standout native that works well when you need both height and seasonal impact.

The foliage is deep green and slightly textured, forming a dense canopy that can be shaped as a large shrub or trained into a small tree. It has a fuller, more substantial presence compared to lower growing ceanothus varieties.

In spring, it produces large clusters of vibrant blue flowers that can cover the plant, creating a striking display. The blooms are highly attractive to pollinators and add a strong seasonal highlight.

Because of its size and growth rate, it’s often used for screening, as a backdrop, or as a focal point in native and drought tolerant designs.

Ceanothus ‘Ray Hartman’ is part of the chaparral plant community, making it well adapted to dry summers and low water conditions once established.

It grows best in full sun and requires well drained soil. It performs best with minimal summer irrigation and good air circulation.

It can reach about 15 to 20 feet tall and wide, especially when trained into a tree form. It is well suited for USDA zones 8 through 10. The foliage is evergreen.

This plant has low toxicity and is generally safe for gardens with pets and children.

The flowers attract pollinators such as bees.

It is generally deer resistant.

Ceanothus ‘Ray Hartman’ fits especially well into native, Mediterranean, and large scale landscape designs, where its size and bloom can be used to anchor a space.

It pairs well with plants like Arctostaphylos densiflorus ‘Emerald Carpet’ to create a cohesive native ground layer, Salvia apiana to introduce a soft, silvery contrast, and Muhlenbergia rigens to add movement and vertical texture at a lower level.

Expert Tip:

Place this in full sun with well drained soil and avoid frequent summer watering, because it is adapted to dry conditions and can decline with excess moisture. Allowing it to establish in lean conditions will result in a healthier, longer lasting plant. This is one of the more stately Ceanothus and really makes a strong visual impact in the landscape of you want height.
