Varnished gum is a small, cold-hardy alpine shrub or mallee (up to about 4 m) native only to mountainous west and southwest Tasmania. It is a species of eucalypt, not a common garden plant, and is grown mainly by specialist collectors in cool climates.

About
Eucalyptus vernicosa, commonly known as varnished gum, is a species of shrub or a mallee that is endemic to mountainous areas of Tasmania. It has smooth greyish bark, crowded, egg-shaped to elliptical or round leaves, flower buds singly or in groups of three in leaf axils, white flowers and hemispherical or bell-shaped fruit.
Where it grows
Eucalyptus vernicosa is endemic to Tasmania, and is only found in alpine regions in the west to southwest, including Cradle Mountain. It grows between 700m and 1350m above sea level, usually on peaty acid soils on top of quartzite or sandstone bedrock. It is usually found above the tree line, and can be a dominant component of alpine heath communities, along with Richea, Athrotaxis, and Orites. This habitat typically has high average rainfall varying from 1000mm to 2500mm per year, and very cold winters with continuous frosts and snow for several months. The harsh climate and nutritiously poor soils probably explain the small size and tough leaves.
