Eucalyptus badjensis, Big Badja Gum, will reach a height of at least 20 metres. The solitary trunk has persistent rough bark on the lower level. Upper parts are smooth, white, green or grey. Leaves are 20 centimetres long, 1.5 centimetres wide, lance-like and leathery.
Flowers are one centimetre across, white and carried in threes. Flowers may appear throughout the year and are both conspicuous and profuse. Native bees visit the flowers. Fruits are bell-shaped with exerted valves.
E. badjensis occurs on the Great Dividing Range, NSW in the vicinity of Big Badja Hill, southern NSW. The species is local common but has restricted distribution. Big Badja Gum is classified as rare. Some populations are protected in a national park.
E. badjensis is probably too large for suburban gardens. On rural properties the species could be cultivated in shelterbelts, windbreaks or as a “stand alone” specimen.
Propagate from seed.
The type specimen was collected in 1924 at an altitude of 1200 metres five kilometres south of Big Badja Mountain. At that time the species was known as “Gully Ash”.
