Ceanothus Blue Mound 5 Litre Pot

Ceanothus ‘Blue Mound’ – Compact Californian Lilac with Neat, Mounded Form

Ceanothus ‘Blue Mound’ is a compact and reliable evergreen shrub, prized for its neat, rounded habit and vibrant blue flowers. In late spring to early summer, it produces dense clusters of small, bright blue blooms that cover the plant, creating a strong, eye-catching display.

The glossy, dark green foliage forms a dense mound, giving the plant structure throughout the year even when not in flower. Its tidy, bushy growth makes it particularly well suited to smaller gardens, where it provides colour without becoming too large or unruly.

Compared to more spreading or vigorous ceanothus varieties, ‘Blue Mound’ offers a more controlled and compact shape, making it ideal for borders, rockeries, or low-maintenance planting schemes.

Thriving in full sun, it performs best in free-draining soil and is well suited to coastal conditions, tolerating wind and drier environments once established. Like most ceanothus, it benefits from a sheltered position away from cold, drying winds.

Easy to grow and low maintenance, it requires only light pruning after flowering to maintain its shape and encourage fresh growth.

Compact, colourful, and dependable, Ceanothus ‘Blue Mound’ is an excellent choice for adding vibrant spring colour and year-round structure to the garden.
