A coastal California native shrub with fine-textured foliage and abundant clusters of small blue flowers in spring. Highly drought-tolerant once established and well-suited to sandy, seaside gardens.

Why grow it

Maritime Ceanothus fills a specific ecological niche for coastal and sandy sites where many ornamental shrubs struggle. Among California native Ceanothus species, it is notably compact and fine-textured, making it useful where space is limited or a finer visual quality is desired compared to larger cultivars. Its salt and sand tolerance, combined with minimal water needs once established, makes it a practical choice for seaside gardens where spray exposure and poor soil are typical constraints.
