Ceratostigma willmottianum Forest Blue


Chinese Plumbago

Stunning blue flowers followed by red autumn foliage

A must have shrub for the late summer garden. Exotic looking Hardy Plumbago is easy to grow and has clusters of flat, bright blue flowers emerging from spiky brown buds from August onwards. Beautiful autumn leaf colours of red, plum purple and orange shades complete the picture before the leaves fall to reveal brown twiggy mounds through the winter months.


Very unfussy on soil types and suitable for sun or part shade, Ceratostigma 'Forest Blue' is also suitable for a large container.


Use a good quality general purpose compost for container growing and raise the pot on 'pot feet' through the winter months to help with drainage. Plant in the garden in any good soil and cut back long growths to shape in late spring if required.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
