Canberra gardens face hard frosts and hot, dry summers. Here's how we choose planting that handles both and holds through summer with almost no input.
Canberra asks a lot of a garden. Frosts linger into spring, then summer arrives with weeks of 35-degree days and very little rain. Plenty of gardens look wonderful in October and are struggling by February. The ones that don't were designed for both extremes from the start. Here's how we do it.
Start with the site, not a plant list
Soil, aspect and the way heat moves across a block matter more than any individual plant. A north-facing bed against a dark wall is a different climate from a shaded southern corner three metres away. At our Narrabundah project the courtyard sat in a warm, reflected-heat pocket between dark cladding and paving — so the palette was chosen for exactly that, not for 'Canberra' in general.
Lean on silver and grey
Silver and grey foliage is nature's sunscreen: the colour comes from fine hairs or a waxy coating that reflects heat and holds moisture. It's why dichondra, westringia, cushion bush and lavender turn up again and again in our work — they look considered against dark cladding, and they shrug off a dry February. At Yarralumla they carry the whole garden against the house's standing-seam black.
Use grasses for movement and resilience
Ornamental grasses give a garden softness and motion, and most of the ones we use are deeply drought-hardy once established. They also pair well with clipped structure plants — buxus, topiary standards — which give the scheme its bones through winter when everything else has pulled back.
Go fully dry where the site demands it
Some courtyards are too hot and too hard for a conventional garden to be happy. Our Dugan Street project answered a blank, sun-baked courtyard with a desert palette — barrel cacti, columnar cactus, dracaena and spiky grasses in white pebble — and it is engineered for a decade of near-zero maintenance. Low-water doesn't have to mean sparse; it can mean sculptural.
Mulch deep, water smart
Deep mulch keeps roots cool and stops the soil drying out between waterings. Integrated drip irrigation on a zoned, smart controller delivers water to the root zone, not the air, and lets thirstier beds and tough ones run on different schedules. That combination is what lets a Canberra garden hold through summer with almost no input — it's standard on every garden we build.
Plant in spring, establish before the heat
Timing is half the battle. Planting in spring gives roots months, not weeks, to settle before summer tests them. Leave it until November and the first heatwave arrives before the garden is ready for it. We've written more on why spring is the moment to plan in the journal.
Design for the whole year
Low-water isn't the only brief; a garden still has to earn its place in winter. Deciduous trees that colour hard in autumn, structure that holds its shape through frost, and planting chosen for the block rather than the catalogue — that's a garden built for Canberra's actual climate, not an idealised one.
