Caryopteris 'Kew Blue' – A Stunning Blue-Flowering Shrub for Late Summer Colour
Caryopteris 'Kew Blue' is a hardy, deciduous shrub known for its striking, aromatic foliage and vibrant blue flowers that bloom in late summer. Often referred to as Bluebeard, this plant is perfect for adding colour, structure, and texture to your garden, particularly in mixed borders, wildlife gardens, and as a low hedge. Its compact size and long-lasting blooms make it a fantastic choice for gardens looking to extend their flowering season into the autumn months.
Seasonal Beauty & Growth
Spring:
- In spring, 'Kew Blue' begins to push out small, fragrant, silvery leaves, which provide an attractive backdrop for other plants in the garden.
- The foliage grows densely, creating a tidy mound that will gradually take shape throughout the growing season.
Summer:
- By late summer, the plant produces clusters of vibrant blue flowers, which cover the bush in a profusion of colour. These small, tubular flowers attract bees, butterflies, and other pollinators, making it a fantastic addition to wildlife gardens.
- The aromatic foliage releases a slight fragrance when crushed, further enhancing the sensory appeal of the plant.
Autumn:
- The blue flowers linger well into autumn, providing a bright burst of colour as other plants begin to fade. The grey-green leaves may take on subtle autumnal hues, adding depth to the garden.
Winter:
- The plant dies back in winter, leaving behind a neat, bare structure. While not evergreen, it is easy to prune back in early spring to encourage new growth for the next season.
