About this plant

  • Description

    A low-growing, spreading ceanothus with glossy green foliage and abundant clusters of soft blue flowers in late spring. Often referred to as a ‘rainbow’ effect plant when in full bloom, it brings a fresh, coastal feel to borders, walls and ground cover planting.

  • Why we like it

    Ceanothus thyrsiflorus var. repens is perfect for adding vibrant colour to sunny, sheltered spots while also covering ground with ease. Its spreading habit makes it especially useful for banks and walls, where it softens edges and provides seasonal interest with minimal effort.

Planting & care

Help it thrive

Planting guide

Plant in spring in well-drained soil in a sunny, sheltered position. Avoid heavy clay unless improved with grit. Water regularly during establishment, then reduce as the plant becomes drought tolerant.

Care tips

Prune lightly after flowering to maintain shape. Avoid hard pruning into old wood. Keep soil free-draining and do not overwater once established.

Winter care

Hardy in milder UK areas but may need protection in colder regions. Plant in a sheltered spot away from cold winds and avoid waterlogged soil. Mulch around the base to protect roots in winter.
