12 Australian native plants that thrive in degraded soil
Many of the most resilient and ecologically valuable plants in the Australian flora evolved specifically in soils that are nutrient-depleted, compacted, low in organic matter or heavily disturbed.
These plants are built for soil just like that. In many cases, they perform noticeably worse when the soil is amended, fertilised or enriched. Understanding this is the foundation of working with them successfully.

What degraded soil actually is
Degraded soil is where structure, biology and chemistry have been altered to a point where it no longer functions as a living system. Most suburban gardens in Australia contain at least some degraded soil as a result of construction, compaction, the removal of vegetation cover, chemical applications and years of intervention.
The signs are consistent across different soil types:
| Sign | How to identify it |
|---|---|
| Compaction | Soil that resists penetration, pools water after rain and feels solid underfoot |
| Low biological activity | No earthworms, few invertebrates, no visible fungal threads, soil that smells flat rather than earthy |
| Hydrophobia | Water beading on the surface and running off rather than soaking in |
| Poor structure | Soil that either forms a hard ball or falls apart when squeezed, with no aggregated crumble |
| Nutrient depletion | Low organic matter, low phosphorus, low nitrogen, often following years of bare soil or chemical lawn treatment |
For conventional garden plants, this is a problem. For the plants on this list, it is simply the starting condition. See our soil care guide for a detailed breakdown of Australian soil types and how to read what you are working with first.
Why amendment is often the wrong instinct
Australian soils have weathered in place for hundreds of millions of years, producing landscapes that are among the most nutrient-poor on earth. The plants that evolved here developed extraordinary efficiency at extracting what they need from almost nothing. Adding compost, fertiliser or organic matter raises nutrient levels beyond what these plants are adapted to handle. The result is rapid, soft growth that is more susceptible to disease, more vulnerable to drought stress and shorter-lived than a plant grown in the lean conditions it was designed for.
12 Australian native plants that thrive in degraded soil
1. Ruby saltbush (Enchylaena tomentosa)
All mainland states · Arid · Dry temperate · Mediterranean
Ruby saltbush is one of the toughest plants in the Australian flora. It grows across an enormous range, from the arid interior to dry temperate and Mediterranean coastal zones. The small, fleshy leaves are silver-grey and the plant produces a constant supply of red and yellow berries that are an important food source for birds and small reptiles.

It establishes readily from seed scattered directly onto unimproved ground, requires no irrigation once established and responds well to light trimming. It is also one of the few Australian natives that tolerates mildly saline soils, which makes it valuable in gardens where salt has accumulated. Ruby saltbush performs best in lean, free-draining soils and declines in enriched conditions.
2. Yellow buttons (Chrysocephalum apiculatum)
All mainland states · Wide climate range
Yellow buttons is among the most genuinely widespread native groundcovers in Australia. Its small, bright yellow button flowers appear from spring through to autumn and the silver-grey foliage provides textural interest year-round. It is a plant that actively colonises disturbed and degraded ground which makes it one of the most useful plants available for gardens starting from a difficult baseline.
It spreads by layering as stems contact bare soil, which means it gradually fills bare patches over successive seasons without any intervention. In amended or highly fertile soils it tends to become rank and short-lived. In lean, well-drained soils it is long-lived and self-maintaining.
3. Spiny-headed mat rush (Lomandra longifolia)
Queensland · NSW · Victoria · SA · WA · Tasmania · Wide climate range
Lomandra is one of the most ecologically useful plants available for degraded suburban soils. Its dense root system physically breaks compaction over time, improves soil aeration and accumulates organic matter at the base of the clump as older leaves break down. It occurs naturally in a wide range of soil types and conditions and is particularly associated with disturbed and recovering ground in eastern Australia.
Lomandra requires no fertiliser, no amendment and no supplemental watering beyond the first summer. It is also a valuable nesting material source for small birds. See our guide to restoring a degraded garden for how lomandra fits into a broader recovery planting.
4. Chocolate lily (Arthropodium strictum)
Victoria · NSW · SA · Dry temperate · Grassland and grassy woodland
The chocolate lily is one of the most rewarding and underused plants for degraded temperate soils. Its small, star-shaped mauve flowers appear in spring on slender stems above strap-like foliage, and in warm conditions they carry a faint chocolate-vanilla scent that gives the plant its common name. It occurs naturally in dry grassland and grassy woodland on clay and loam soils that are seasonally dry and low in nutrients.
It is a plant of the understorey, comfortable in the dappled shade of eucalypts as well as in full sun, and it naturalises readily in lawn areas that are allowed to grow out in spring. It dies back in summer and re-emerges in autumn.
5. Billy buttons (Craspedia variabilis)
Victoria · NSW · SA · Tasmania · Dry temperate to alpine
Billy buttons produces one of the most architecturally distinctive flowers in the Australian flora — a perfect golden sphere on a long, slender stem. It occurs naturally in grassland, grassy woodland and subalpine areas across southeastern Australia, invariably in soils that are low in nutrients, seasonally dry and often shallow over rock or clay hardpan.
It is a short-lived perennial that self-seeds reliably in open, disturbed ground, which means a single plant typically establishes a self-sustaining colony over two to three seasons without any intervention. The flowers dry on the stem and hold their shape and colour for months, making them one of the most popular natives for dried arrangements.
6. Knobby club rush (Ficinia nodosa)
All mainland states and Tasmania · Coastal to inland temperate
Knobby club rush is a clumping rush with dark green, cylindrical stems and small brown seed heads that provide year-round structural interest without any maintenance. It occurs naturally across an enormous range: coastal dunes, estuarine margins, degraded paddocks and disturbed ground. It is one of the few plants that performs equally well in pure sand and in heavy compacted clay, which makes it exceptionally useful for gardens where the soil type is uncertain or variable.
It tolerates salt spray, periodic waterlogging and extended drought once established. The dense clumping form provides nesting cover for small ground-dwelling birds. It requires no fertiliser, no irrigation beyond the first season and no pruning beyond the occasional removal of dead outer stems. Plant into unimproved soil, mulch the surface and leave it alone.
7. Tall bluebell (Wahlenbergia stricta)
All mainland states · Wide temperate range
The tall bluebell is one of Australia's most beautiful wildflowers. Slender, branching stems carry clear sky-blue bell flowers from spring through summer and the plant self-seeds prolifically in open, disturbed ground. It occurs naturally across a wide range of temperate Australia in grassland, grassy woodland and along roadsides and track edges, invariably in nutrient-poor soils with minimal organic matter.
It is a short-lived perennial particularly suited to the gaps and bare patches that characterise recovering or newly planted gardens. It is also a valuable nectar source for small native bees. Scatter seed directly onto disturbed soil or allow it to naturalise from nearby plantings. Like billy buttons, it thrives where most plants fail.
8. Purple coral pea (Hardenbergia violacea)
Queensland · NSW · Victoria · SA · Tasmania · Wide temperate range
Hardenbergia is one of the most useful and reliable native pea flowers available for degraded soils. Its vivid purple-violet flowers appear in late winter and early spring when almost nothing else is flowering. It occurs naturally across a wide range of temperate Australia in sandy, gravelly and rocky soils in heath and dry sclerophyll communities — always in lean, well-drained conditions.
As a legume, hardenbergia fixes atmospheric nitrogen through root nodule bacteria, which means it gradually improves soil fertility over time. This makes it particularly valuable as an early pioneer plant in degraded situations as it stabilises and enriches the soil for subsequent plantings. It can be grown as a climber on fences and structures, as a sprawling groundcover on banks and slopes, or as a loose shrub in open positions.
9. Prickly moses (Acacia verticillata)
Victoria · SA · Tasmania · NSW · Cool to warm temperate
Prickly moses is a dense, prickly wattle with pale yellow cylindrical flower spikes in spring. It is one of the most ecologically valuable wattles for degraded and disturbed ground. Its dense, thorny growth provides nesting and refuge habitat for small birds in situations where other shrubs have not yet established, and like all wattles it fixes nitrogen through root nodule bacteria, actively improving the soil it grows in.

It occurs naturally in a range of soil types across the cooler parts of southeastern Australia. It is also useful as a temporary screening plant in new gardens, growing quickly enough to provide structure and privacy while longer-lived plants establish around it. It has a natural lifespan of around ten to fifteen years, after which it can be removed as the surrounding planting matures. See our no-dig garden guide for how pioneer plants like prickly moses fit into a staged establishment approach.
10. Native pigface (Carpobrotus rossii)
WA · SA · Victoria · Tasmania · Coastal and inland dry temperate
Native pigface is a succulent groundcover with triangular fleshy leaves and large, vivid magenta to pink flowers. Carpobrotus rossii is the southern and western Australian species, distinct from the commonly planted C. glaucescens of the east coast. It grows on sandy and gravelly soils, cliff faces and degraded coastal ground with no organic matter and high salt exposure.
Once established it spreads rapidly to cover bare ground, suppresses weeds through shading and provides both nectar for bees and edible fruit for birds and small animals. It requires absolutely no amendment, no fertiliser and no supplemental watering once established in appropriate conditions.
11. Native rosemary (Westringia fruticosa)
NSW · Victoria · SA · Wide temperate range · Coastal to inland
Westringia is one of the most reliably useful shrubs available for degraded suburban soils across southeastern Australia. Its grey-green foliage, white to pale lilac flowers and compact habit make it a natural fit in both native and mixed plantings, and its resemblance to rosemary has made it one of the more widely planted Australian natives in recent decades. It occurs naturally on coastal headlands and cliffs in NSW, in thin, rocky, salt-exposed soils with essentially no organic matter.
In the garden, it establishes readily in compacted clay, pure sand and degraded suburban fill soils without amendment, tolerates moderate frost, salt spray and extended drought and flowers reliably year-round. It is also a consistent performer for native bees.
12. Silver banksia (Banksia marginata)
Victoria · SA · Tasmania · NSW · Cool to warm temperate
Banksia marginata is the most climate-adaptable and soil-tolerant of the banksias, occurring naturally from sea level to over 1500m altitude across Victoria, SA, Tasmania and coastal NSW. It grows in sandy heath soils, shallow rocky soils, seasonally waterlogged flats and dry hillsides. Its cylindrical yellow flower spikes appear in autumn and winter, providing nectar at a time when most other plants have finished flowering.
As a proteaceous plant, it develops specialised cluster roots that are extraordinarily efficient at extracting phosphorus from depleted soils. Adding phosphorus to the soil around a silver banksia can kill it within weeks even at low application rates. Plant into unimproved soil, apply a coarse native mulch to the surface, water in once and leave it to establish. In appropriate conditions it requires nothing further. See our banksia growing guide for species selection across different climate zones.
Getting these plants established
The instinct to prepare soil before planting is deeply ingrained, but for the plants on this list it can cause more harm than good. The correct approach is minimal intervention: open a planting hole, place the plant at the correct depth, backfill with the removed soil and apply a coarse native mulch to the surface. No compost, no fertiliser, no soil conditioner.
Water in deeply at planting and then water once a week for the first summer, reducing to once a fortnight in the second summer and then relying on rainfall thereafter. The establishment period is the only time these plants need consistent support. Once their root systems are developed they will look after themselves in the conditions they were selected for.
For gardens recovering from more severe degradation — construction fill, heavily compacted ground, chemically treated soils — our guide to restoring a degraded garden covers the staged establishment approach in detail, including which pioneer species to use first and how to sequence plantings for the best long-term outcome.
For gardens where ground preparation is genuinely minimal — bare patches, disturbed areas, cleared sections — native seed bombs scattered directly onto the surface are an effective way to establish a new garden without any soil preparation at all.
