A hot February week can quickly show which parts of a garden are working too hard. If your lawn is crisping up, pots need daily attention and flowering plants collapse by lunchtime, it is time to choose drought tolerant garden plants that suit the way Australian summers actually feel.
Drought tolerant does not mean a plant never needs water. Every new plant needs regular watering while it settles in, and extreme heat can test even the toughest native. The real advantage is that, once established, these plants can cope with longer gaps between drinks without losing their shape, colour or will to live.
What makes a plant drought tolerant?
The best dry-garden performers have built-in ways to hold onto moisture or find it. Some have small, grey or leathery leaves that reduce water loss. Others have fleshy leaves, deep root systems or naturally grow in exposed Australian conditions. Mediterranean plants also tend to be a strong fit for sunny, free-draining gardens.
Your local conditions still matter. A coastal Sydney courtyard, a frost-prone Canberra block and a Perth garden on sandy soil each need a slightly different approach. Look beyond the plant label’s water rating and consider sun, soil drainage, wind and overnight winter temperatures before adding anything to the trolley.
12 drought tolerant garden plants worth planting
Kangaroo paw
Kangaroo paw is made for gardeners who want a native statement without constant fuss. Its strappy foliage and upright flowers bring bright colour to sunny borders and large pots, with shades ranging from red and orange to yellow and green. Give it full sun, good drainage and room for air movement. Trim spent flower stems down at the base to keep the plant tidy.
Grevillea
Grevilleas are a practical choice when you want flowers, birds and an easy-going Australian native in the same plant. There are compact ground-cover forms, low mounding shrubs and taller screening varieties, so check the mature size before buying. Most prefer full sun and free-draining soil. Avoid overfeeding, particularly with high-phosphorus fertilisers, as many natives are sensitive to them.
Westringia
Often called native rosemary, westringia earns its place in gardens that need structure. The soft grey-green foliage handles heat, wind and clipping well, making it useful for low hedges, borders and poolside planting. Small pale flowers appear through much of the year in suitable conditions. It is not the showiest plant in the garden, but it makes everything around it look more organised.
Lomandra
For a low-maintenance edge, mass planting or difficult strip beside the driveway, lomandra is hard to beat. Its grass-like leaves soften hard landscaping and tolerate dry spells once established. Many varieties cope with full sun, although selections vary, so match the plant to your spot. A late-winter tidy-up, removing old leaves and spent stems, is usually enough to refresh it.
Pigface
Pigface is one of the most useful drought-tolerant plants for hot, exposed ground. Its fleshy leaves store water, while bright daisy-like flowers add colour through warmer months. Use it where it can spill over a retaining wall, cover a bare bank or fill a broad pot. It needs sun and sharp drainage, not a rich, constantly wet position.
Correa
For areas that receive some shade rather than blazing afternoon sun, correa is a smart native option. Its bell-shaped flowers are a welcome sight in the cooler months and are popular with birds. Correаs generally handle dry periods once established, but they are not the best choice for a brutally hot western-facing bed with reflected heat all day. Give them protection from harsh exposure and avoid soggy soil.
Lavender
Lavender brings fragrance, soft colour and a classic clipped look to sunny paths and garden beds. It likes light, well-drained soil and is happier with occasional deep watering than frequent shallow splashes. Humid climates can be more challenging, especially where airflow is poor, so avoid crowding plants together. Choose a variety suited to your climate and prune lightly after flowering rather than cutting into old bare wood.
Rosemary
Rosemary is a garden workhorse that also earns its keep in the kitchen. Upright varieties make useful informal screens, while trailing forms suit walls and pot edges. Full sun and drainage are non-negotiable. Once established, rosemary usually handles dry weather well, but a plant in a small pot will dry out much faster than one planted in the ground.
Olive trees
An olive can bring a calm, silvery look to a courtyard or sunny backyard. These trees prefer full sun and free-draining soil, and mature plants cope well with dry conditions. They are best treated as a long-term feature rather than a quick filler plant. If you are hoping for fruit, check whether the variety suits your climate and whether pollination requirements apply.
Agapanthus
Agapanthus is tough, leafy and reliable for sunny gardens, especially in larger blocks where you need coverage without high maintenance. Blue, purple or white flower heads rise above the foliage in summer. It can spread in favourable conditions, so use it thoughtfully and deadhead spent flowers if you want to limit self-seeding. In small gardens, choose compact forms rather than planting a vigorous variety right beside a path.
Bottlebrush
Bottlebrush brings bold flowers and bird activity to a dry-tolerant planting scheme. Compact varieties suit smaller gardens, while larger forms can become excellent feature shrubs or informal screens. Most prefer sun and tolerate dry periods after establishment, although regular watering during their first summer gives them a far better start. Prune after flowering if you want a denser shape.
Succulents such as aloe and echeveria
Succulents are the obvious choice for sun-baked pots, balcony gardens and spots where watering is likely to be forgotten. Aloes offer architectural leaves and often flower in winter, while echeverias create neat rosettes in a wide range of colours. The trade-off is cold and wet weather: they need a very free-draining mix and should not sit in a saucer of water after rain.
Set drought tolerant plants up for success
Buying the right plant is only half the job. A drought-tolerant plant that is placed in heavy, waterlogged soil or planted in the middle of a heat-reflecting concrete corner can still struggle. Prepare the site first, especially if your soil is compacted clay or poor sand.
Water deeply at planting time, then keep the root zone consistently moist for the first few weeks. During the first summer, check new plants regularly and water deeply when the soil below the surface begins to dry. Deep watering encourages roots to move down into cooler soil; quick daily sprinkles encourage shallow roots that are less prepared for heat.
A layer of mulch around the plant helps hold soil moisture, suppress weeds and keep roots cooler. Keep mulch a few centimetres away from stems and trunks so moisture does not sit against the plant. In pots, use a quality potting mix, choose a container with drainage holes and remember that dark pots in full afternoon sun can become extremely hot.
Design for lower water use, not just tougher plants
The most water-wise gardens group plants with similar needs together. Put thirsty leafy plants closer to a tap or irrigation line, and use tougher shrubs, grasses and succulents in the hottest outer edges. This makes watering quicker and stops dry-loving plants from receiving more water than they need.
Use plants at their mature size, too. A tiny shrub can look cheap on planting day, but a garden packed too tightly soon competes for water and needs more pruning. Repeating a few reliable varieties often looks cleaner, costs less to maintain and gives each plant enough space to establish properly.
If you are buying online, start with the conditions you can offer: full sun or part shade, ground or pot, compact or screening, flowering or foliage. Buy My Plants makes it easier to shop by the role a plant needs to play, rather than choosing only by the prettiest photo.
A garden that uses less water should still feel generous. Choose a few plants you genuinely enjoy seeing from the kitchen window or front gate, plant them well, and let their first season be about settling in rather than surviving.
