About
Eucalyptus kochii, commonly known as oil mallee, is a species of mallee, sometimes a tree, and is endemic to Western Australia. It has rough, flaky or fibrous bark on the trunk, smooth grey bark above, linear to narrow lance-shaped adult leaves, flower buds in groups of nine to fifteen, white flowers and urn-shaped fruit.
How to grow it
This eucalypt is cultivated in plantations for the production of eucalyptus oil. The distilled oil has a very high content of cineole (83-94%).
Where it grows
Oil mallee is found on flats, depressions, rises and along roadsides from Kondut to near Pindar in the Avon Wheatbelt and Yalgoo biogeographic regions of Western Australia where it grows in sandy-loamy-clay soils over laterite or granite.
