Go beyond the planting
Selecting landscaping materials in a white garden is perhaps more important than in other spaces and should never fight with the planting. Avoid strong colours such as red brick or paving with hints of pink in it, and go for a neutral colour. Grey stone paving and chippings, or a simple, light oaty gravel works best.
Choose carefully accessories such as furniture, features and structures. Bleached-out timber, neutral colours and even dark greens will work with flowers. Avoid using white paint in a white garden and let the plants do the talking.
Look for neutral finishes to pots. Even terracotta probably has too much colour. Stone and metallic grey finishes work well. Whiteglazed pots may work well, but try to hide or soften them with plenty of green foliage.
Screen off your white garden if other areas aren’t white. Think about creating a ‘room’ with hedging or trellis to keep the eye contained within an area. If this isn’t possible, then use non-white plants in the other areas as too much white will dilute the impact of your white garden.
Think about the overall balance as things can start to go wrong in a white garden when you put in a plant or object that has, say, strong foliage colour that fights with the scheme – so be ruthless. If a plant self-seeds or an odd-coloured bulb pops up in the wrong place, you know what you have to do!
