Lemon-scented gum

Lemon-scented gum is Corymbia citriodora, a fast-growing Australian tree with aromatic foliage. The South Australian Botanic Gardens Plant Selector gives a height range of 10–35 metres and spread of 8–20 metres; the RHS notes trees reaching about 30–40 metres in the wild. ## Landscape Use Plant this large eucalyptus relative only where there is room for its mature crown and height. Its smooth pale bark, slender lemon-scented leaves, and cream-white flowers give it year-round structural interest. [The Botanic Gardens of South Australia profile](https://plantselector.botanicgardens.sa.gov.au/Plants/Details/17829) records its size range, erect spreading habit, soil textures, and winter-to-spring flowering. [The RHS profile](https://www.rhs.org.uk/plants/324302/corymbia-citriodora/details) describes the scent, bark, fast growth, and full-sun exposure; [Kew confirms the Corymbia citriodora name and Myrtaceae family](https://powo.science.kew.org/taxon/986336-1). ## Growing Conditions The South Australian profile recommends full sun, clay or loam soil, and minimal supplementary watering. It lists cream flowers in winter and spring. Choose a planting site that can accommodate a very large mature tree and its spreading crown. ## Maintenance Water during establishment and then adjust supplemental irrigation to local rainfall and soil. Allow clearance for the broad canopy and inspect the tree as it matures. Avoid routine pruning that would remove its natural form unless site safety or clearance requires it.
