About
Cymbopogon bombycinus, or citronella grass (also called silky oil grass) is a species of perennial grass in the family Poaceae that is native to Australia.
Where it grows
Cymbopogon bombycinus is found mostly in southwestern areas of Australia, in tropical and subtropical regions of Queensland, New South Wales, the Northern Territory, and Western Australia. The species occurs on sandy and stony soils along stream banks or on alluvial flats, and occasionally in eucalyptus woodlands.
