10 frost-tolerant Australian native plants for winter gardens
Frost is often treated as a limitation, but it is really a filter. Gardens in frost-prone areas of Australia can rely on native plants that are genuinely adapted to cold, drawn from alpine, tableland and inland regions where winter temperatures regularly drop below zero. These plants are built for frost.
The ten species below are less commonly recommended than the usual frost-tolerant choices. They bring structure, texture, fragrance and seasonal interest to winter gardens and support wildlife.

1. Snow gum (Eucalyptus pauciflora)
Snow gum is the most cold-adapted eucalypt in Australia and one of the most visually distinctive trees. At altitude it survives temperatures below -20°C, heavy snow load and the intense radiation frost of open alpine sites. In garden settings it brings that same toughness to frost-prone areas of Victoria, NSW, the ACT, Tasmania and South Australia where other trees struggle.

The smooth bark cycles through cream, grey, olive and copper tones through the year. Cream flowers appear in summer and attract honeyeaters and insects. It is one of the few eucalypts that can reasonably be planted in a frost-prone garden close to a house.
2. Alpine mint bush (Prostanthera cuneata)
Alpine mint bush is one of the finest small shrubs for cold gardens and one of the most underused. It grows naturally in the subalpine zones of Victoria, NSW and Tasmania in rocky, exposed positions above 1000m where snow is common. In gardens its small, aromatic leaves release a strong peppermint fragrance and masses of small white flowers appear in summer.

It stays compact with light tip pruning using sharp secateurs after flowering. It needs excellent drainage, so a raised position or sloped aspect suits it well. Through winter the aromatic foliage holds its colour and fragrance even in the coldest conditions.
What frost tolerance actually means
For the plants in this list, frost tolerance refers to genuine cold hardiness which is the capacity to survive sustained overnight frosts, ground frost and in some cases snow. The most important factor for any plant in a frost-prone garden is drainage: waterlogged soil that freezes around roots causes more damage than air temperature alone. A well-drained site, a coarse mulch layer and shelter from the worst frost pockets will extend the performance of every plant here.
3. Silver banksia (Banksia marginata)
Silver banksia is the most widespread and climate-adaptable banksia in Australia, found from coastal headlands to alpine heathland across Victoria, NSW, South Australia and Tasmania. Its altitudinal range alone tells the story: populations growing above 1500m in the Victorian Alps and Snowy Mountains survive conditions that most banksias would not. In the garden this translates to genuine cold hardiness combined with wildlife value.
The creamy-yellow flower spikes appear through autumn and into winter — a particularly valuable time for nectar-feeding birds. It handles poor soils, coastal exposure and dry conditions once established. Avoid high-phosphorus fertilisers and remove any dead flower spikes with loppers to keep the plant tidy.
4. Dusty daisy bush (Olearia phlogopappa)
Dusty daisy bush is one of the most rewarding cold-climate shrubs. It produces masses of daisy flowers in late winter through spring, covering the plant so densely that the grey-green foliage is almost invisible beneath them. In a frost-prone garden it flowers at exactly the moment the garden most needs something happening.

It grows naturally in sheltered gullies and woodland margins across Tasmania, Victoria and southern NSW. Prune by up to one-third with secateurs immediately after flowering to prevent it from becoming leggy. The flowers attract native bees and small butterflies through late winter when pollinator activity is just beginning to resume.
5. Mountain grevillea (Grevillea alpina)
Mountain grevillea is extraordinarily variable — some forms are prostrate groundcovers, others reach two metres. What all forms share is genuine cold hardiness from alpine and subalpine provenance in Victoria, NSW and the ACT. In the cold garden it provides nectar for honeyeaters at exactly the time they most need it.

Flower colours span cream, yellow, orange, pink and red and the nectar load is high relative to size. It handles poor sandy soils and dry conditions once established. Prune lightly after the main flush of flowering with sharp secateurs to encourage dense regrowth. For a broader guide to growing grevilleas across climate zones, see our grevillea growing guide.
6. Native iris (Patersonia occidentalis)
Patersonia's delicate purple-blue flowers last only a day each, but they appear in succession over weeks. Through winter and early spring, when most other plants are dormant, a clump of native iris produces a persistent display.
It grows naturally in heathland and dry sclerophyll woodland across southern and eastern Australia, tolerating both frost and summer dry. The strappy foliage provides structure through winter even when the plant is not in flower. Plant in well-drained soil with a slim trowel and leave largely undisturbed. It combines beautifully with native grasses and low-growing groundcovers in naturalistic plantings.
7. Kunzea (Kunzea ambigua)
Tick bush covers itself so completely in small white honey-scented flowers that the foliage almost disappears. It handles heavy frost, drought, coastal exposure and poor sandy soils without complaint. It was one of the first Australian native plants introduced to cultivation in England, which reflects how reliable it is in cold, difficult conditions.
The flowers attract an extraordinary range of insects making it one of the highest-value insect-habitat plants in the cool temperate flora. It grows through winter as a dense, fine-leaved evergreen providing screening and structure, then transforms completely when spring arrives. Prune by up to one-third after flowering with loppers to keep it compact.
Mulch before winter, not after
Apply a 7–10cm layer of coarse organic mulch around all plantings before winter arrives. Mulch applied before the ground cools moderates soil temperature through the coldest months, significantly reducing the freeze-thaw cycling that damages roots. A garden knife is useful for working mulch precisely around tightly planted groundcover areas without disturbing root zones.
8. River mint (Mentha australis)
River mint is a spreading, aromatic groundcover with genuine culinary and medicinal use in Australian Aboriginal culture. It grows naturally along creek lines, shaded gullies and damp woodland margins across eastern and southern Australia, which tells you exactly what it needs: consistent moisture, good organic matter in the soil and shelter from the hottest sun.
It spreads by runners and can be divided easily with a hand fork in autumn or spring to extend plantings. The small white to pale mauve flowers attract native bees through the warmer months.
9. Scoparia (Richea scoparia)
Richea scoparia is a spiky, heath-like shrub with linear leaves and vertical flower spikes in shades of red, orange, pink, gold and white. It is endemic to the alpine and subalpine zones of Tasmania, which makes it one of the most cold-adapted plants on this continent.

This is a specialist plant that requires specific conditions: moist, acidic, well-drained soil. In Tasmanian gardens and in the cool, wet highland gardens of Victoria and NSW it is genuinely achievable and spectacular. In drier, warmer or more alkaline gardens it will struggle.
10. Pimelea (Pimelea ligustrina)
Tall rice flower is one of the most elegant small shrubs in the cool temperate Australian flora. It produces dense, rounded clusters of small white flowers from late winter through spring, on a plant with neat, opposite, glossy leaves and a naturally tidy compact habit. The flowers are lightly fragrant and attract native bees.

It grows naturally in cool temperate woodland and open forest across Victoria, NSW and Tasmania. It is naturally compact enough that it rarely needs heavy pruning. It suits formal and informal plantings equally and pairs beautifully with other cool-climate natives like olearia, prostanthera and the compact forms of grevillea.
