A white garden is an exciting possibility in Australia – not just for your festive brunches and lunches, but also in the evenings when it glows under the moonlight and its perfumes can be at their most intoxicating.

White gardens are rarely just white. Pops of colour come from yellow-centred daisies or pink-tinted fuchsias. Then there are the different shades of white, from cool, or warm and creamy, to the pale mellow yellow of vanilla or the luminous glow of ivory.
While foliage is the anchor of your floral display, it’s a point of contrast. Warm, limey greens can sit with dark olives, and silver or white foliage such as dusky miller can transform the ground into a whirl of lace.
How to design a white garden
Here’s 8 tips for creating a white garden.
1. Add lots of greenery to make the white pop
Masses of green foliage in many shapes, textures and hues – from deep forest green to zesty lime – add energy to a garden. White is the ideal colour to go with green, as it instantly adds contrast and freshness.
2. Add white furniture
A dreamy white daybed and table keep the white theme flowing when the greenery is dominant.
3. Add some yellow
Throw in pops of strong yellow in the form of a vase filled with sunflowers. The Easter lilies maintain the white theme.
4. Add hydrangeas
No white garden is complete without bouncing bundles of hydrangeas spilling over a low box hedge. Mix the round balls of H. macrophylla alongside conical-shaped H. paniculata. They begin flowering in spring and can last through to autumn, especially if you deadhead them when they begin to fade. This means your shrubs will produce more blooms instead of putting their energy into producing seeds.
Tips for growing white hydrangeas
Hydrangeas are an easy way to add white to your garden, as there are so many types (see below).
While they can show green or cream hints, they maintain their whiteness whatever your soil pH. So if yours go pink or blue, they aren’t true white.
- If you do want colour, you get pink hydrangeas when your soil is alkaline. You can get deeper pinks or red pompoms bouncing off big, lush leaves by adding lime to soil.
- If you prefer blue flowers, turn your soil acidic by adding aluminium sulphate.
- You can get both of these at nurseries.
5. Hanging baskets
White geraniums in window boxes and a hanging basket are an obvious choice, but the perfect touch is the variegated white and green ivy falling from the tub of hydrangeas.
6. Choose pavement over grass
A huge benefit of paving is you can use different sizes and colours to create beautiful and intriguing designs. There are no limits to your creativity!
7. Add some fragrant flowers
Not all hydrangeas are perfumed – although H. paniculata does have a strong scent – so mix roses in with them to create a sensual, fragrant garden.
8. Try going vertical
It’s an old idea but it still works to great effect if you mass your plants on the steps of an old wooden ladder. White geraniums highlight the delicate appearance of the flowers, something that’s not apparent with the bright red ones. a box hedge maintains its green colour all year round.
