South Coast Blue grows 8'-10' high and 5' wide so it is an excellent choice for that narrow spot in the yard that needs an eye-catching shrub. It has dark blue flowers and deep green foliage. The foliage is one of the best parts about this plant and really sets this plant apart  although the deep blue flowers are excellent too. We have found it to be fast growing. It was introduced to us by Greg Rubin of California's Own Native Plant Design  and is a hybrid between 'Trewithen Blue' (a type of Ceanothus arboreus) and Ceanothus 'Frosty Blue'.
