Frost Tolerant Plants — Hardy, Beautiful Choices for Cold Australian Gardens

About

Gardening in a frost-prone climate should never mean settling for a bare, colourless winter garden. Australia's frost-affected regions — from Melbourne's inner suburbs and the Dandenong Ranges to Canberra's high plains, the Adelaide Hills, and inland Victoria and New South Wales — are home to some of the country's most beautiful gardens, filled with plants that don't just survive winter cold but genuinely thrive in it. At Online Plants , our frost tolerant collection is curated specifically for gardens that experience temperatures down to -5°C. Every plant in this range has been selected by our horticultural team for reliable cold-weather performance — from evergreen hedging shrubs and flowering natives to ornamental trees, groundcovers , and perennials that deliver year-round structure and seasonal colour through even the sharpest overnight frosts. Browse with confidence: all plants are backed by our exclusive 30-day grow guarantee and delivered fresh to your door across VIC, ACT, NSW, QLD and SA. Which Parts of Australia Experience Frost? Frost in Australia occurs when ground-level temperatures drop below 0°C, typically on still, clear winter nights when there is no cloud cover to retain heat. The main frost-affected regions are: • Melbourne metropolitan area: Light to moderate frosts are common from June through August, particularly in the outer eastern, northern, and western suburbs. The CBD and inner suburbs experience fewer frost nights due to the urban heat island effect. The Dandenong Ranges, Yarra Valley, and Macedon Ranges experience significantly heavier and more prolonged frosts. • Canberra and ACT: Australia's most consistently frost-affected major city. Canberra averages 40–60 frost days per year and regularly records minimum temperatures of -5°C to -8°C. Gardens here require genuinely frost-hardy plants — not just frost-tolerant varieties. • Adelaide Hills and Barossa Valley: Moderate frosts from June through August. Frost-tolerant plants perform well
