Overview of California lilacs
The genus Ceanothus, also known as wild lilac, California lilac or simply ceanothus, comprises approximately 55 species of woody shrubs native to both eastern and western North America. Most of these species live in western North America, mostly in California. However, at least nine species are native to Western Oregon and are an important part of summer-dry forests, oak woodlands, and chaparral. Most species are evergreen shrubs, which range widely in habit from prostrate to sprawling or large erect shrubs, with some even forming small trees. Ceanothus are also nitrogen-fixing shrubs and do not require nitrogen fertilizers. Because of this they are best utilized in summer-dry, lean, well-drained soils.
Since blue is a hard color to find for gardens, Ceanothus are one of a kind because they let gardeners use this rare color in a big way.
Many species bloom in the spring and early summer. The flowers can be white or pink, but most are different shades of blue. Many gardeners find it hard to find blue plants, but Ceanothus are special because they let gardeners use this hard-to-find color in a big way. Plus, Ceanothus flowers may have a light scent and are very appealing to many types of pollinators.
In selecting Ceanothus for your landscape, a few things to be mindful of are size, pruning and watering regimes. Some Ceanothus grow very quickly to become large shrubs, which can easily outgrow their allotted space. Carefully check the size of the Ceanothus at purchase and provide it with sufficient space to grow unimpeded to maturity. Pruning these plants excessively to control size, especially evergreen types, often leads to dieback. The semi-deciduous hybrid cultivars are much more forgiving of pruning. Also keep in mind that as mentioned, Ceanothus native to the west are adapted to summer-dry environments and so are naturally summer-dormant. They should only be planted in un-irrigated locations in the garden. Watering them in summer leads to rampant growth and possible root disease.
