Problem free
After the long, hot and dry Summer of 2018 I am convinced that this shrub is indestructible. We have four. Two were bought as standards and planted in the front garden in the sunny but very windy and exposed site and they are now, after five years, about 4m high trees. There is a little bit of wind scorch in Spring but we have them trimmed lightly after flowering and they recover with new growth.The other two were bought two years ago as small pyramids and were planted in the back garden in a West facing mixed shrub border and are already 3 metre tall narrow pyramids. In our experience they are as fast growing as Fatsia japonica and they look lovely planted next to them too. My neighbour keeps hers under control in a rather small pot on her patio and it looks equally gorgeous. We may have found an ideal plant to replace the box we lost.
