Ceanothus - a closer look
Family Ramnacea- Ceanothus species at Clearwater Color Nursery
Ceanothus, also known as Wild Lilac, or Buckthorns, are a common native to the California landscape. The name comes from the Greek, Keanthos meaning ‘thorny plant’. Most Ceanothus species are frost and drought hardy and deer resistant, unless in very dry years. Apparently they have a reputation for being short lived, due to some landscapers believing that they need soil amendments, fertilizer, or irrigation, all of which WILL cause the plant to lose its ability to survive in the California landscape, for which it is supremely successful. Some species are Actinorhizal, meaning they fix nitrogen in a symbiotic relationship with the bacteria Frankia, living in nodes attached to their roots.
We are currently growing 15 species of Ceanothus. Please check our availability on our website www.clearwatercolor.com for the species that are currently available. There are 3 different growth patterns of Ceanothus, Prostrate, or creeping, shrubby, or bush form, and thirdly, upright. We will start with the Prostrate plants, and move on up!
