Hearst Ranch Buckbrush (Ceanothus hearstiorum), also known as San Simeon Ceanothus, is a low-growing California native evergreen shrub prized for its exceptionally flat, spreading habit. Its small, textured green leaves form a dense carpet, while fragrant clusters of medium-blue flowers create a stunning display in spring. The blooms attract bees, butterflies, and other beneficial pollinators. Naturally adapted to coastal California conditions, this drought-tolerant shrub thrives on well-drained slopes and sunny banks, providing attractive groundcover with minimal summer watering once established.
