The best drought tolerant plants Australia gardeners can grow in Sydney are hardy natives such as westringia, kangaroo paw, lomandra and correa, planted in autumn or spring and watered deeply while they establish. The biggest mistake is assuming drought tolerant means no water, because every new plant needs regular watering for its first season.
This guide covers the plants to choose, how to plant them, what suits flowers and small spaces, and what help costs in Sydney.
Key points
- Plant in autumn or spring, when soil is warm and rain helps roots settle before the heat of summer.
- You need free-draining soil, mulch and a trigger-nozzle hose, and you must follow Sydney Water’s Water Wise Guidelines, which allow watering before 10 am and after 4 pm.
- Check labels for mature size and frost tolerance, because hardy does not always mean frost-proof or compact (indicative — check the plant label).
- A Sydney gardener typically charges about $52 to $115 per hour for planting, mulching and tidy-ups (October 2026).
What are drought tolerant plants Australia gardeners use?
| Term | Meaning | Why it matters |
|---|---|---|
| Drought tolerant | A plant that survives long dry spells once its roots are established. | It still needs watering in its first season. |
| Drought resistant | Often used as a loose synonym for drought tolerant. | Check the label for how long a plant copes without water. |
| Hardy plants | Plants that handle tough conditions such as heat, wind, poor soil or light frost. | Hardiness varies, so match the plant to your suburb. |
| Low maintenance | Plants needing little pruning, feeding or watering. | Even low maintenance plants need yearly tidying. |
| Native | A plant that evolved in Australia. | Natives often suit local conditions, though some need good drainage. |
When to plant drought tolerant plants in Sydney
| Season | What to do | Why |
|---|---|---|
| Autumn (Mar–May) | Plant most natives and mulch. | Warm soil and cooler air let roots establish before summer. |
| Winter (Jun–Aug) | Plan beds and prepare soil; plant hardy types only. | Cold, wet clay can rot roots of frost-tender plants. |
| Spring (Sep–Nov) | Plant and feed with a native-friendly fertiliser. | Growth surges, but watering must keep up. |
| Summer (Dec–Feb) | Water new plants deeply and provide temporary shade. | Young roots dry out quickly in heatwaves. |
What you need
| Item | What it is for | Tip |
|---|---|---|
| Spade and mattock | Digging holes in clay or compacted soil | Loosen the sides of each hole so roots can spread. |
| Organic mulch | Holding moisture and cooling roots | Keep it clear of the stems to prevent rot. |
| Slow-release native fertiliser | Feeding new plants | Choose a low-phosphorus product for natives and follow the label exactly. |
| Trigger-nozzle hose or drip line | Watering new plants | Required by the Water Wise Guidelines; never leave a hose running unattended. |
| Soil wetter | Helping water enter dry or hydrophobic soil | Seasol and similar products help in dry spells; follow the label. |
| Gloves and secateurs | Planting and light pruning | Wear eye protection when cutting spiky foliage. |
Drought tolerant plants Australia: step by step
- Choose plants by mature size, sun and soil, reading the label for height, spread and frost tolerance (indicative — check the plant label).
- Mark out beds so taller plants sit at the back and low plants edge the front, leaving room for growth.
- Dig each hole about twice as wide as the pot and no deeper than the root ball.
- Loosen circling roots gently, set the plant so the top of the root ball is level with the soil and backfill firmly.
- Water slowly to settle the soil, using a trigger nozzle before 10 am or after 4 pm.
- Spread organic mulch over the soil, keeping it back from stems.
- Water deeply every few days for the first few weeks, then taper off as new growth appears (indicative — check the product instructions).
- Feed lightly in spring and prune after flowering to keep plants dense and tidy.
Australian drought tolerant native plants
Natives suit Sydney’s sandstone and clay soils well, but most hate soggy roots, so drainage matters.
- Plant westringia (coastal rosemary) for a hardy, clipped hedge or low shrub that copes with salt wind on the Northern Beaches.
- Choose lomandra for tough, grassy clumps that handle clay and dry spells in western Sydney beds and borders.
- Add kangaroo paw in full sun and well-drained soil, and keep water off the leaves to limit ink spot.
- Use correa for shaded, dry corners, where its tubular flowers feed honeyeaters in winter.
- Pick banksia species for sandy soils, and avoid heavy fertiliser, which can harm many native roots.
Drought tolerant flowering plants
Colour does not have to cost water. These plants flower reliably once established.
- Choose grevilleas for long flowering and bird visits, and prune lightly after flowers fade.
- Plant lavender in full sun and sandy soil, and trim after flowering to keep it compact.
- Add native daisies such as paper daisy for bright ground-hugging colour in spring.
- Use pelargoniums in pots and sunny beds, where they flower through warm months with minimal water.
- Try bottlebrush for a hardy flowering screen, and check the mature size on the label (indicative — check the plant label).
Small drought tolerant plants Australia suits
Smaller gardens, courtyards and pots need compact varieties rather than large shrubs.
- Use dwarf westringia varieties for compact hedging that stays tidy in a courtyard or beside a driveway.
- Choose mat rush and dianella for low, strappy foliage that fills gaps beneath trees.
- Plant succulents such as echeveria in terracotta pots, with a gritty mix and drainage holes.
- Grow native ground covers like native violet or pigface to suppress weeds between pavers.
- Pick a dwarf grevillea or kangaroo paw for pots, which dry out faster, so check moisture weekly.
Hardy garden plants and low maintenance garden plants
If you want a garden that survives holidays and busy weeks, build it around tough plants and good mulch.
- Mulch every bed each year to cut watering and weeds, topping up as it breaks down.
- Group plants with similar water needs so you are not over-watering the tough ones.
- Fit a smart or drip irrigation system, which may run between 10 am and 4 pm under Sydney Water’s guidelines.
- Keep plants away from paths and edges, and choose hardy varieties that do not need constant clipping.
- Leave only the plants you can maintain, and book a regular gardener for tidy-ups.
Common drought tolerant plant mistakes
- Planting in heavy clay without a mound or grit, then losing natives to root rot after winter rain.
- Skipping watering after planting, because the label says drought tolerant.
- Over-fertilising natives with high-phosphorus products, which can damage sensitive roots.
- Choosing by flower colour alone and ignoring mature size, so plants crowd paths within a few years.
- Piling mulch against stems, which holds moisture at the base and invites rot.
- Mixing thirsty lawn grasses and tough plants in the same bed, then over-watering both.
When to call a gardener or licensed specialist
- You need large shrubs or trees pruned above ladder height, so book a qualified arborist and check council rules first.
- Branches sit near power lines, which is work for qualified professionals only.
- Insect problems are damaging plants, so book a licensed pest controller.
- Paid weed spraying around beds needs a licensed applicator; routine garden maintenance has an exemption.
- You need irrigation plumbing connected to the mains, so book a licensed plumber.
- You want regular maintenance, mulching and green waste removal from a local gardener.

Yes, while they establish. New plants need regular, deep watering for their first season, using a trigger nozzle before 10 am or after 4 pm. Once roots are established, most survive dry spells with occasional soaking in extreme heat.
What are the best small drought tolerant plants in Australia?
Dwarf westringia, mat rush, dianella, native violet, pigface and compact succulents suit small gardens and pots. Choose varieties by mature size on the label, and use gritty soil and good drainage to keep roots healthy.
Which drought tolerant flowering plants are low maintenance?
Grevillea, kangaroo paw, lavender, bottlebrush and paper daisy flower well with little care once established. Mulch each year, prune lightly after flowering and check plant labels for mature size and frost tolerance.
