Caryopteris clandonensis ‘Dark Knight’ is a fantastic mid-sized shrub, bearing masses of eye-catching deep blue flowers in late summer and autumn.
It forms a mound of slightly toothed, grey-green leaves with silver hairs on the undersides and is perfect for growing in large containers or in a sunny border.
Happy in most soil types, provided it's not waterlogged, this is a very easy-going little shrub.
Useful for adding blue to the garden in late summer and autumn.
The flowers are a magnet for bees.
