Double hedges can look really smart. 

Like in the attached photo, Camellia Setsugekka is the taller hedge at the back, and in front there is the beautifully contrasting foliage colour and texture of Buxus Koreana. I like using this variety of buxus because it naturally wants to stay extremely bushy (hardly any trimming is needed to keep this variety in shape and looking smart). Camellia setsugekka would be the biggest selling flowering hedge in N.Z. and I think rightly so, it’s one of the best varieties on the market - masses of single flowers in autumn winter and the petals even drop cleanly so you’re not left with big brown mushy flowers on the bush. It’s a great variety for use to block out the wind or pleaching, for screening out the neighbours.
