About

Eucalyptus radiata, commonly known as the narrow-leaved peppermint or Forth River peppermint, is a species of tree that is endemic to south-eastern Australia. It has rough, fibrous to flaky bark on the trunk and larger branches, smooth grey bark on the thinner branches, lance-shaped to curved or almost linear leaves, flower buds in groups of eleven to twenty or more, white flowers and cup-shaped, hemispherical or shortened spherical fruit.

Where it grows

Narrow-leaved peppermint grows in forest and woodland, usually in cooler or wetter habitats. It occurs in New South Wales south from near the Queensland border, in the Australian Capital Territory, to the Wombat State Forest, Great Otway National Park and ranges of South Gippsland in Victoria. It also occurs in Tasmania where it is restricted to the catchment of the Forth River. Subspecies robertsonii is restricted to montane and subalpine forests of north-eastern Victoria.

Uses

Eucalyptus radiata has six known chemotypes of essential oil. The leaves are distilled for cineole and phellandrene based eucalyptus oils. E.radiata was the first eucalyptus species to be commercially utilized for oil by Melbourne pharmacist, Joseph Bosisto, in 1854 as "Eucalyptus amygdalina".
