Eucalyptus nobilis

This species belonging to the white gum group is closely related to E. viminalis, but comes from the New England Tablelands where it grows at altitudes mostly above 3,000' where it is exposed to snow and heavy frost. It has the distinction of probably being the tallest growing tree in New South Wales, the tallest one having been measured at 258'. It is virtually unknown in cultivation but can be expected to grow very vigorously and upright, with smooth white bark over most of the trunk, and adapt to a wide range of climates - it might do well in the South. A wild guess at hardiness might be 10 - 15 °F. Try something different!
