Ceanothus ‘Blue Mound’
Californian Lilac 'Blue Mound'
Compact yet striking, Californian Lilac ‘Blue Mound’ carries glossy, wavy-edged green leaves and produces dense clusters of bright blue flowers in late spring, often returning for a second flush later in the year. Its mound-forming habit makes it perfect for medium spaces and mixed borders. Awarded the RHS | Award of Garden Merit, it is also drought resistant and loved by bees. If you’ve been looking for colour that returns again in autumn, this could be the shrub you need.
