Ceanothus 'Concha' is one of the most popular and reliable California Lilac varieties, prized for its spectacular display of deep blue flowers in late spring and early summer. This hardy evergreen shrub produces dense clusters of rich, dark blue blooms set against glossy, dark green foliage, creating a stunning focal point in any garden. When in full flower, the entire plant becomes alive with visiting bees and pollinators, making it a wonderful choice for wildlife-friendly planting schemes.

With its naturally dense, arching habit, Ceanothus 'Concha' is ideal for growing against a sunny, sheltered wall or fence, as a standalone specimen shrub, or as part of a mixed border. It thrives in well-drained soil and a warm, sunny position, and once established, it is both drought-tolerant and low-maintenance. This variety holds the RHS Award of Garden Merit (AGM), a mark of its outstanding garden performance.
