Lemon Eucalyptus is a tall tree, growing to 35 metres in height (but sometimes taller), from temperate and tropicalnorth eastern Australia. It is also known as lemon-scented gum, blue spotted gum, lemon eucalyptus andeucalyptus citriodora.
Lemon Eucalyptus has smooth, pale, uniform or slightly mottled bark, white to coppery in summer, and a conspicuously narrow-leaved crown which smells strongly of lemons. Pear-shaped buds are borne in clusters of three, formed in the corner of leaf and stem junctions, whilst fruit (capsules) are urn-shaped. The bark is smooth for the entire height of the tree, often powdery, shedding in thin curling flakes.
It prefers lighter, slightly acidic loamy soils and occurs in dry sclerophyll forest and woodlands in hilly country. Lemon Eucalyptus has a lignotuber. Flowering has been recorded in January, April, May, June, July, August, October and December.
Plants of C. citriodora are naturalised in the Darling Range near Mundaring, Western Australia and by planting to suburban New South Wales and Victoria.
