Xanthorrhoea Johnsonii, also known as Xanthorrhoea grass tree, is a perennial plant that is native to Southeastern Australia. This plant has more than 25 species, and can reach up to 5 m tall; meanwhile, some species are low-growing plants of Xanthorrhoea. This plant is also known as blue grass and gum grass in Australia because some of its species produce gum, and these plants are pollinators that attract insects like butterflies. Australians used this plant for many purposes, such as tool making, using it as glue, and using it to varnish furniture.
