Ceratostigma willmottianum ‘Forest Blue’
Ceratostigma willmottianum ‘Forest Blue’ is a popular deciduous shrub with a well-deserved RHS AGM. From August to October, its wiry red-tinted stems play host to a profusion of cobalt-blue flowers. The green summer foliage turns to vivid shades of burnt orange and red as autumn progresses, bringing a welcome splash of colour to fading borders. A low, spreading shrub, ‘Forest Blue’ deserves a prominent position towards the front of a sunny border, or planted against a wall. Height: 100cm (39). Spread: 150cm (59).
