Eucalyptus gunnii
Also called Cider Eucalypt Tree, Cider Gum Tree, White Swamp Gum
Cider gum (Eucalyptus gunnii) is a fast-growing, cold-hardy eucalyptus tree from Tasmania, grown as an ornamental tree, often with a smooth white or mottled bark. Its key to success is full sun, good drainage and tolerance of cold, though it can grow large and is best given space.
Eucalyptus gunnii, commonly known as cider gum, is a species of flowering plant in the family Myrtaceae. It is a small to medium-sized tree with mostly smooth bark, lance-shaped to egg-shaped adult leaves, flower buds in groups of three, white flowers and cylindrical to barrel-shaped fruit.
This plant has gained the Royal Horticultural Society's Award of Garden Merit. This species is noted for exceptional cold tolerance for a eucalyptus (to −14 °C, exceptionally −20 °C for brief periods) and is now commonly planted as an ornamental tree across the British Isles.
The fragrant leaves give off essential oils when they are creased or burned, which are used in different forms (floral composition, infusion, tincture, oil, etc) to treat many respiratory diseases, rheumatism, migraines, fatigue and as antiseptic.
Cider gum is native to woodland in Tasmania, where it occurs on the plains and slopes of the central plateaux and dolerite mountains at altitudes up to about 1,100 m (3,600 ft), with isolated occurrences south of Hobart. It grows in higher altitudes where the summers are mild and winters cold with many frost and heavy snow, and annual average rainfall is about 1,800 mm (71 in).
