Mountain Ash (Eucalyptus regnans)

Description

Eucalyptus regnans, known variously as mountain ash, swamp gum, or stringy gum, is a species of Eucalyptus native to Tasmania and the state of Victoria in southeastern Australia. It is the tallest flowering plant and one of the tallest trees in the world, second to the coast redwood (Sequoia sempervirens). A straight-trunked tree with smooth grey bark and a stocking of rough brown bark to 5-20 metres (16-66 ft) above the ground, it regularly grows to 85 metres (279 ft), with the tallest living specimen, the Centurion, standing 99.82 metres (327.5 feet) tall in Tasmania. The white flowers appear in autumn. Victorian botanist Ferdinand von Mueller described the species in 1871.
