GRAND BLEU ® is a dense, bushy rounded shrub. Its growth is regular. It is suitable for container growing.
Its abundant and late flowering spreads from August to October. The flowers have long stamens and are of a remarkable deep dark blue, which is highlighted by the bright, dark green characteristic foliage. Like all Caryopteris, the foliage gives off a turpentine smell when touched.
GRAND BLEU ® attracts attention, when it is associated with shrubs or brightly coloured perennials. It is very suitable for planting in large quantities in public spaces, or as a sole shrub in gardens of moderate size.
