Caryopteris clandonensis ‘Dark Knight’ is a fantastic small 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 containers or towards the front of a sunny border. Its flowers are a magnet for bees. Happy in most soil types, provided it's not waterlogged, this is a very easy-going little shrub.
