Creating a drought-tolerant garden in Brisbane is not only an eco-friendly choice, it also gives you a beautiful outdoor space that flourishes with minimal maintenance. By selecting the right plants, you can be confident your garden will hold up through dry spells and shrug off the restrictions that arrive with every long summer.
To make plant selection easier, we have grouped our top picks into the four categories that actually matter when you are planning a water-wise bed: Australian natives, succulents and architectural plants, drought-tolerant perennials and shrubs, and ornamental grasses. Choose one or two from each group and you end up with a layered, resilient planting rather than a collection of unrelated survivors.
Everything below is chosen for Brisbane's warm, humid summers and dry winters, and almost all of it will also do well through subtropical New South Wales and southeast Queensland more broadly. For the bigger picture on water-wise design, our guide to creating a waterwise garden covers irrigation, mulch depth and soil preparation in detail.
1. Australian natives: hardy and resilient
Native plants are adapted to Australian rainfall patterns and low-phosphorus soils, which makes them the natural backbone of a drought-tolerant garden.
Grevillea
Grevillea is a diverse group of native plants with more than 350 species, ranging from small groundcovers to large trees. Their vibrant flowers, which come in a wide range of shapes and colours, attract bees, butterflies and nectar-feeding birds.
Grevillea is an excellent choice for a drought-tolerant garden in Brisbane because it adapts to a variety of soil types and asks for very little water once established. Popular choices include Grevillea 'Robyn Gordon', Grevillea 'Superb' and Grevillea 'Honey Gem'. Prune your grevilleas regularly to maintain their shape and encourage prolific blooming; our grevillea care guide explains how hard you can safely cut them back.
Banksia
Banksias are iconic Australian natives with unique cylindrical flower spikes, ranging in colour from yellows to reds and maroons. They are superbly adapted to Australian conditions, which makes them a natural fit for drought-tolerant gardens in Brisbane.
Banksias attract birds and other wildlife, adding a dynamic element to the garden. Choose drought-resistant varieties such as Banksia spinulosa, Banksia ericifolia and Banksia integrifolia. Banksias want well-drained soil, full sun to partial shade, and almost no fertiliser to thrive.
Westringia
Westringia is an Australian genus of evergreen shrubs with fine, grey-green foliage and delicate flowers, usually white or pale blue. Westringia fruticosa, the coastal rosemary, and Westringia 'Wynyabbie Gem' are the two most useful drought-resistant forms.
Westringias are genuinely low maintenance, needing minimal water once established. They thrive in well-draining soil and tolerate full sun to light shade, and regular pruning keeps them compact and dense, which is why they turn up so often in our list of low-maintenance plants that thrive in full sun.
Kangaroo paw
Kangaroo paws (Anigozanthos) are instantly recognisable for their fuzzy, tubular flowers, which come in red, yellow, orange and green. These drought-tolerant perennials suit Brisbane gardens well, surviving long periods without water.
Popular varieties include Anigozanthos 'Bush Diamond', 'Bush Gold' and 'Bush Bonanza'. Kangaroo paws want well-drained, sandy soils and full sun. Remove dead flower stems at the base to encourage further blooming and reduce ink spot disease.
2. Succulents and architectural plants: water-wise and sculptural
Succulents store water in their leaves, stems or roots, which is exactly the adaptation you want in a hot Brisbane courtyard. They also bring strong shapes that hold a garden together visually.
Agave
Agaves are versatile succulents that add structural interest to a garden. Their rosette-forming leaves come in a range of sizes, shapes and colours, making a bold statement in any space. They are native to the arid regions of North, Central and South America, which is why they cope so easily with Brisbane's dry spells.
Low-maintenance, drought-tolerant options include Agave attenuata, Agave americana and Agave angustifolia. Agaves need well-draining soil and infrequent watering to prevent root rot; our roundup of agave garden ideas shows how to use them in beds, pots and gravel gardens.
Yucca
Yuccas are architectural plants with sword-shaped leaves and tall spikes of creamy white flowers. Native to the Americas and the Caribbean, they are well suited to Brisbane's dry conditions. Varieties such as Yucca elephantipes (spineless yucca), Yucca filamentosa (Adam's needle) and Yucca gloriosa (Spanish dagger) all make striking additions to the garden.
Yuccas grow well in free-draining soil and prefer full sun to light shade. Be careful when handling them, as some species have sharp, pointed leaf tips; the spineless forms are the safer choice near paths and play areas.
Euphorbia
Euphorbia is a diverse group of more than 2,000 species ranging from low groundcovers to large shrubs and trees. Many euphorbias are succulent and drought-tolerant, which makes them an ideal choice for a Brisbane garden.
Euphorbia tirucalli (pencil tree or Firesticks) and Euphorbia millii (crown of thorns) are two popular choices, both with unusual form and very low water requirements. Euphorbias want free-draining soil and tolerate anything from full sun to partial shade. Wear gloves when pruning, as the milky sap irritates skin and eyes.
Sedum and echeveria
Sedums, also known as stonecrops, are succulent groundcovers and perennials that come in a range of forms, colours and textures. Varieties such as Sedum 'Autumn Joy', Sedum reflexum (blue spruce stonecrop) and Sedum album (white stonecrop) suit Brisbane's climate, needing free-draining soil and full sun. Echeverias, the classic rosette succulents, do the same job at ground level and are perfect for rockeries, pots and the front edge of a dry bed.
3. Drought-tolerant perennials and shrubs: colour that lasts
Perennials and flowering shrubs stop a water-wise garden from looking like a gravel pit. These are the ones that keep flowering when the rain does not arrive.
Lavender
Lavender is a fragrant, drought-tolerant perennial herb that adds a touch of elegance to the garden. Depending on the variety, the blooms range through purple, blue and white.
Lavender prefers free-draining soil and full sun, and needs little water once established. Varieties that grow well in Brisbane include Lavandula angustifolia (English lavender), Lavandula stoechas (Spanish lavender) and Lavandula dentata (French lavender), which is by far the most reliable of the three in our humidity. Prune after each flush to encourage bushy growth and prolonged flowering.
Oleander
Oleanders are flowering shrubs that are both drought-tolerant and heat-resistant, which makes them a sensible choice for Brisbane's climate. They produce abundant tubular flowers in pink, red, yellow or white through the warmer months, surviving with very little water in free-draining soil and full sun.
Popular varieties include Nerium oleander 'Hardy Red', 'Sister Agnes' and 'Apple Blossom'. Please note that oleander is toxic if eaten, so be cautious where children and pets have access.
Salvia and penstemon
Salvias cover an enormous range of leaf shapes, sizes and flower colours, and they are among the best plants available for attracting bees, butterflies and birds. They need minimal watering, which makes them an ideal filler in a drought-tolerant bed. Penstemon is the other reliable performer, thriving in Brisbane's warm climate and tolerating extended dry periods while producing attractive tubular flowers for perennial borders and mixed plantings.
4. Ornamental grasses: texture and movement
Ornamental grasses introduce texture and movement to the garden, with the added benefit of being genuinely drought-tolerant once they are away.
Lomandra
Lomandra, the spiny-headed mat-rush, is a hardy evergreen native that adds texture while tolerating both drought and poor soils. It is one of the toughest plants in the trade, holds its shape without clipping, and works equally well massed along a driveway or used as an understorey under trees. Our lomandra longifolia care guide covers spacing and the once-every-few-years cut back that keeps clumps fresh.
Blue fescue and fountain grass
With its compact mounding habit and blue-grey foliage, Festuca glauca, or blue fescue, is a fantastic addition to a water-wise garden. It is low maintenance and can be used as a groundcover, an edging plant, or planted en masse for a striking effect. For height and movement, fountain grass and the burgundy-leafed Pennisetum setaceum 'Rubrum' add rich colour and fluffy flower plumes, thriving in well-drained soil with only occasional watering once established.
Design ideas for drought-resistant landscapes
Plant choice is only half of it. A water-wise garden also depends on how the pieces are arranged.
Layering: combine different plant heights, textures and colours, using drought-tolerant trees, shrubs, grasses and groundcovers to create a dynamic, visually engaging garden rather than a flat bed of one species.
Xeriscaping: group plants with similar water requirements together, use water-efficient irrigation, and let the toughest plants take the hottest, driest corners. Hydrozoning like this is the single biggest saving you can make on a garden's water bill.
Rock and gravel gardens: rock features or gravel mulch lend a naturalistic look, provide definition and structure that complements drought-tolerant plants, and reduce water loss from the soil surface far more effectively than bare earth.
Care tips for a drought-tolerant garden
Even the toughest plants need help in their first year. These practices make the difference between plants that survive and plants that thrive.
Soil preparation: before planting, amend the soil to improve both water retention and drainage. Organic matter or well-aged compost boosts moisture retention while still allowing excess water to drain away.
Watering: drought-tolerant plants still need water during establishment and in prolonged dry periods. Water deeply and infrequently rather than lightly and often, which trains roots to go down instead of sideways.
Mulching: a layer of organic mulch maintains consistent soil moisture, suppresses weeds and regulates soil temperature. Keep it 5cm to 7cm deep and clear of plant stems.
Fertilising: use a slow-release, balanced organic fertiliser sparingly. Over-fertilising produces soft growth that is more water-hungry, not less, and native plants in particular want a low-phosphorus formulation.
