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, maintaining its beautiful green foliage year round.
ID Characteristic
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 throughout the winter seasons.
PropagationPropagate in mid-summer by taking semi-ripe cuttings from the current season's growth. Collect in the early morning using a sharp knife to cut pieces 10-15 cm in length. Remove all leaves from the lower third and pinch out any soft terminal growth. Dip into a number 2 rooting hormone, insert into trays or pots of cutting compost and water well. Place in a propagator with bottom heat set at 15°C with or without mist; rooting should occur in 4-6 weeks.
CultivationMoist, alkaline soils with full sun to partial shade.
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.
