The Story
Plant Bio
Santalum acuminatum, commonly known as the sweet quandong, is an evergreen large shrub or small tree native to arid and semi-arid regions of mainland Australia. It features a sparse canopy of pale to grey-green, lanceolate leaves and operates as a root hemiparasite, drawing water and nutrients from neighbouring host plants.
This species produces small, green-white to red-brown flowers in terminal clusters, followed by edible, bright red fleshy fruits with a distinctive tart flavour. The hard, pitted stone inside contains a kernel that is toxic if consumed raw in large quantities but has historically been used for its high oil content.

Planting
How to Grow
- Select a planting site in full sun with exceptionally free-draining soil, avoiding any areas prone to waterlogging.
- Ensure a suitable host plant, such as an Acacia, is established within one to two metres of the planting hole.
- Dig a hole twice the width of the root ball and plant the quandong at the same depth as it was in the container.
- Water in lightly to settle the soil, but refrain from regular heavy watering or applying high-phosphorus fertilisers.
Pro Tip
Establish the quandong within one to two metres of a vigorous host plant, such as an Acacia, to ensure its root system can parasitize the host for long-term survival.
