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 plentiful intense 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 flowers are excellent too. We have found it to be fast growing. South Coast Blue Lilac is very versatile and manageable and we have enjoyed training it on an espalier and pruning some as standards. 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.
