Summer in Australia means long days, strong sun, and hot nights. These conditions make tree selection critical. The right summer flowering trees, shade trees, and drought-tolerant varieties help keep outdoor spaces cool and colourful, reduce heat in urban areas, improve air quality, and support native birds, bees, and pollinators.
Choosing wisely can lower energy bills, protect lawns and gardens from harsh sunlight, and create comfortable spaces for relaxing or entertaining. This guide highlights five top-performing trees for Australian gardens. Each is selected for resilience, low maintenance, and proven benefits. Discover what makes them special, where they thrive, and how to plant and care for them to get the best results.
