About
The blue quandong (Elaeocarpus grandis) is an outstanding pioneering tree, known for its rapid growth, often reaching 5 to 6 metres within a few years. Mature trees can exceed 30 metres in height and have an open canopy that permits light to reach the shorter understory, making it perfect for creating lush tropical plantings beneath.
The blue quandong is recognisable by its distinctive red-pink leaves contrasting with the surrounding green foliage. A large, pale-buttressed trunk supports its massive size. In autumn, the branches are adorned with rows of white flowers, which later transform into bright blue, round fruits.

Fruits and seeds
The blue quandong fruit, often referred to as the native or desert peach, is a staple in the traditional Aboriginal diet. It boasts a higher vitamin C content than oranges.
The fruit typically reaches a diameter of 25-30mm. Traditional Owners would eat the fallen fruit raw or mash the flesh into an edible paste. The pulp of the fruit is sour and slightly bitter. Raw green fruits were picked and buried in the sand for four days, during which they softened, turned blue, and became sweeter and more palatable. Inside, there is a rough, woody stone that contains up to five seeds.
Fun Fact: The woody stones, characterised by their deeply pitted surfaces, are occasionally used for decorative purposes.
The fruits also appeal to birds, such as brush turkeys, and mammals like flying foxes. In Far North Queensland, southern cassowaries (Casuarius casuarius) eat the fruit and aid in seed dispersal through their dung.

During the colonial era, the timber was used for making racing sculls and oars, as well as for cabinet making and interior construction.
