Blue quandong is a large buttressed rainforest tree from northeastern Australia, grown mainly in big gardens and parks rather than small home plots. Its key limitation is its huge eventual size, which makes it unsuitable near drains or in suburban gardens.

About

Elaeocarpus grandis, commonly known as blue quandong, is a species of flowering plant in the family Elaeocarpaceae first described in 1860. It is a large buttressed tree native to the coastal rainforests of northeastern Australia. The validity of this taxon is disputed, with some authorities accepting it and others presenting it as Elaeocarpus angustifolius.

How to grow it

The blue quandong is ideal for large gardens and parks, but its sheer size make it unsuitable for suburban home gardens or planting near drains. About 50 of these trees have been planted throughout the city of Cairns.

Where it grows

The blue quandong grows in well developed tropical and subtropical rainforest, often along watercourses. Its range is the coastal forests from the islands of the Torres Strait, through to the Nambucca River in northeastern New South Wales. In north Queensland the altitudinal range is from sea level to 1,100 m (3,600 ft).
