Australian summers mean long warm days and stretches of 30°C and above. Tree selection matters. The right choices deliver shade, colour and structure while shrugging off heat and dry conditions.

These five trees have been chosen for resilience, low maintenance and their ability to perform across most Australian climates through the hottest months.

Magnolia grandiflora 'Coolwyn Gloss'

Year round dense foliage with large fragrant white flowers across summer. One of the few evergreen magnolias that flowers reliably while delivering full privacy from base to crown.
