About Ceanothus ‘Joyce Coulter’ (Joyce Coulter Ceanothus)

This evergreen shrub is called Ceanothus ‘Joyce Coulter’. It is thought to be a hybrid mix between Ceanothus papillosus variegated roweanus and Ceanothus griseus variegated horizontalis, now called C. thyrsiflorus. Its name ‘Joyce Coulter’ was derived from the wife of John Coulter in 1962, four years after it was developed.  Growing an average landscape size of 2-3′ by 12-15′, this specimen features densely packed elliptical shaped green leaves that grow over 1″ long in size. During spring you will find clusters of 2-3″ long medium blue flowers that emerge peeking out just above its foliage. Commonly known as Joyce Coulter Ceanothus, this shrub is a California native plant that adapts extremely well when used in California landscape designs. Additionally it is known to be drought tolerant, tolerates freezing temperatures and is a more reliable deer deterrent.

Planting and Care Instructions

In coastal climates you should plant this shrub in an area that receives full sun watering infrequently.  In areas with warmer climates you should plant this shrub in part shade with occasional watering during periods of extreme heat. As a general rule of thumb, after planting, water regularly to establish a healthy root system during the first two to three growing seasons. If desired, prune back for shape or size before its blooming season. Occasionally, this groundcover can grow taller than usual but this can be solved by simply pruning the tips of the upright stems.
