about zone 8, or even less, with winter protection). In Tasmania, it reaches heights of 300 feet or more, making it one of the largest trees in the world. Planted in the landscape, it will grow tall and noble—up to 75 feet, and even to 200 feet in ideal conditions. But for those home gardeners wanting to set their sights a little lower, certain nurseries sell a multi-trunked ‘Compacta’ dwarf variety that grows to 30 feet or more.
Juvenile leaves of the blue gum start oval or oblong in shape, with a delightful silvery-green color. They mature quickly, becoming narrow and glossy.

Quite thick and shaggy, it furrows near the base of the tree. The bark peels naturally in long strips or ribbons, making noises similar to paper or linen being torn. Several other members of the eucalyptus family share this peeling bark habit, and for this reason they’ve earned the nickname "stringybarks."
