Ceanothus 'Joyce Coulter' (Joyce Coulter Ceanothus) - A reliable, fast-growing, somewhat mounding evergreen shrub with arching branches 2 to 3 feet tall and 10 to 15 feet, possibly even wider. The slightly elliptic, glossy green leaves vary in length from to 1 inches and the medium blue flowers, borne on 3 to 5 inch-long clusters, add vibrant color for several weeks in spring. Plant in full sun (coastal) and water infrequently to occasionally - is drought tolerant when grown along the coast, but require occasional summer irrigation and part shade in hot, inland sites. Hardy to 15 degrees F. 'Joyce Coulter' is useful as a large-scale, mounding groundcover and is notable for its tolerance of regular irrigation and heavy soils. Thought to be a hybrid between Ceanothus papillosus and Ceanothus griseus (now thyrsiflorus var. griseus), this 1962 introduction was named for the wife of John Coulter, who selected it from his nursery in the Bay Area. We have been growing this great plant at the nursery since 1980.  Information displayed on this page is based on the research conducted about this plant in our library and from reliable online resources. We also note those observations we have made of this plant as it is growing in the nursery's garden and in other gardens, as well how it has performed in the crops out in our nursery field. We will also incorporate comments we receive from others, and welcome to hear from anyone who may have additional information, particularly if they have knowledge of cultural information we do not mention that would aid others in growing Ceanothus 'Joyce Coulter'.
