Grass TreesXanthorrhoea media Xanthorrhoea thorntonii
Commonly known as the Grass Tree (Xanthorrhoea media), is a medium sized grass tree. The flowers are borne on a long spike above a bare section called a scape. The flower spike can measure between 90 cm to 2 metres tall (although the flowers make up approximately 1/6 of the total height of the flower spike).
Pictured on this page is the Xanthorrhoea media growing at The Royal Botanic Garden Sydney.
Xanthorrhoea media occurs from Stony Hill to Hilltop on the central coast of New South Wales, as far north-west as Sandy Hollow. Occurs on sandstone, usually on the drier, more exposed ridges and hillsides.
Thousands of years ago, this coastal region that includes the harbourside area of Sydney CBD was bushland that belonged to the Indigenous Australians of the Gadigal group of the Eora Nation. The area of the Sydney CBD that includes the botanic garden was called ‘Cadi’, which is the name for the grass tree in the Cadi language.
These flowering plants are endemic to Australia and was used by Aboriginal people in a number of ways, including making weapons, cutting implements and for food.
