Buxus sempervirens 'Graham Blandy' (Graham Blandy Boxwood)


Michael's Opinion

‘Graham Blandy’ boxwood is a beautiful multiple purpose shrub. It can be used as an accent when planted by itself, grouped together to form a hedge and can even be used as a screen. Like a lot of boxwoods, the leaves are oblong, new growth is a soft green in the spring then changes to a deep rich green in the summer and autumn and continues to stay green through the winter.

Description and Growing Information

General DescriptionA very fastigiate shrub that grows at a slow rate and thrives in well drained soils.
ID CharacteristicSmall oval leaves, 40 mm in length, beautiful green all year round. The shrub reaches 1.8 m at full maturity and is easily maintained. It produces little white flowers and is deer tolerant.
ShapeA narrow, upright column that is dense, with deep green leaves and reaches about 1.5 m in height.
Landscape‘Graham Blandy’ is commonly used as hedge, but can also be used as a screen when plants are grouped together. With its green foliage all year round it is a great accent shrub in the landscape for the winter season when there is not much colour.
PropagationIt can be propagated by taking stem cuttings in the spring or summer and rooting them. It can also be divided but it is not recommended because it can be challenging.
CultivationDoes best in moist, alkaline soils in full to part-sun. It does need to be protected from strong winds in the winter with burlap or any other protective guard.
PestsCaterpillars, leaf miners and boxwood mites. As of late Boxwood blight has become a major problem both in Europe and most of North America. The fungus Cylindrocladium buxicola causes leaf spots, defoliation and even extensive die-back. The disease can be spread by water splash, tools and footwear and can survive for up to six years in the soil. It thrives in moist, humid environments but is killed when exposed to temperatures in excess of 33 °C for at least a week. The disease also affects Pachysandra, Sarocococca and Buxus balearica, sinica, macowanii, microphylla, bodinieri, glomerata, harlandii, sempervirens and riparia species.
