A very large Australian hardwood, and the tallest of the eucalypts, mountain ash is from the mountain regions of Tasmania and eastern Victoria.
Mountain ash has a straight grain but visible gum veins are common. With its course or stringy texture, it is sometimes referred to as 'stringy gum'. Mountain ash is similar in appearance to alpine ash. The heartwood is pale brown, sometimes pinkish and, like alpine ash, the sapwood is not always clearly distinguishable. A fiddleback marking may occur at the butt.
