About
Alpinia caerulea, commonly known as native ginger or Australian ginger, is an understorey perennial herb in the family Zingiberaceae which grows in rainforest, gallery forest and wet sclerophyll forests in eastern Australia.
Where it grows
The native ginger is endemic to New South Wales and Queensland, Australia. The natural range is from the Gosford district north along the coast to the tip of Cape York Peninsula and the islands of the Torres Strait (see map of sightings in the External links section below). It grows in coastal and sub-coastal rainforest and wet sclerophyll forest, commonly beside waterways. The altitudinal range is from sea level to around 1,400 m (4,590 ft).
Uses
For the Kuku Yalanji people of far northern Queensland, this plant had many uses – the fruit and rhizomes were eaten, the leaves were used to cover their shelters and to wrap meat when cooking in earth ovens.
