There are some 500 species of eucalyptus that dominate the woods of Australasia. They are all evergreen and generally aromatic. However there are only about 5 or 6 species that are hardy enough to grow in the British Isles and even these can occasionally get damaged by severe frost. The cider gum, a native of Tasmania, is the commonest eucalypt grown in the British Isles and is said to be hardy down to -14oC
Like most of the family, E. gunnii has distinctly different
juvenile and adult leaves. The juvenile leaves are rounded, with a dense blue
bloom, the adult leaves are more linear and a darker green. The juvenile leaves
are much favoured by florists and the species is grown commercially as a coppice
to provide large quantities of the blue juvenile foliage.
There is also a young Eucalyptus in the Global Medicine Garden
