Lemon Scented Gum - Corymbia citriodora

• The smooth, powdery white trunk is one of the most visually dramatic features of any Australian native tree, creating a striking focal point in the garden across every season.

• Slender grey green leaves release a fresh, distinctive lemon fragrance when brushed or crushed, a characteristic unique to this species among large Australian native trees.

• Its tall, upright oval canopy grows to approximately 30 metres, making it an ideal choice for avenue planting, large open spaces, and landscapes requiring strong vertical structure.

• Creamy white flowers appear in winter, providing an important nectar source for honeyeaters and native bees during the cooler months when few other large trees are in bloom.

• Once established, Corymbia citriodora is highly drought tolerant with low supplementary water requirements, making it well suited to Australia's dry summer conditions.

• It grows in clay, loam, sandy, and well drained soils, making it one of the most soil-tolerant large native trees available to Australian gardeners and landscapers.

• Maintenance requirements are minimal once established. Mulching and occasional watering during dry periods is typically all that is needed to keep the tree healthy.

Corymbia citriodora is a tree of grand scale and presence, best used where its full height, elegant form, and striking white trunk can be fully appreciated:

• Avenue and formal planting: Plant in double rows along driveways and formal garden axes for a breathtaking corridor of white trunks and lemon-scented canopy, one of the classic Australian avenue tree plantings.

• Feature and specimen tree: A bold standalone specimen in large open lawns, parks, or estate gardens where the white trunk and tall oval canopy create an unmistakable year round focal point.

• Park and public open space: Widely used in parks, reserves, and public gardens across Australia for its dramatic appearance, low maintenance, and wildlife value.

• Native and habitat garden: An excellent canopy tree for large scale native garden plantings. Pairs well with Banksias, Grevilleas, and Xanthorrhoea as understorey species.

• Coastal garden planting: Suited to coastal positions in frost-free, warm temperate to subtropical regions of Australia where the canopy provides shelter and habitat.

• Aromatic and sensory garden: The lemon-scented foliage makes this a natural choice for aromatic garden designs and sensory planting schemes.

Q: Is Corymbia citriodora frost tolerant?

No, frost tolerance is rated tender, meaning it is not suitable for areas with regular or heavy frosts without protection. In Melbourne, young trees should be planted in a sheltered, north facing position and protected from frost during the first few winters of establishment. Established trees can handle light, occasional frosts more readily.

Q: How tall does the Lemon Scented Gum grow?

Corymbia citriodora can grow to approximately 30 metres at full maturity, with a spread of more than 10 metres.

Q: When does Corymbia citriodora flower?

Corymbia citriodora flowers in winter, producing masses of small creamy-white blooms that are an important nectar source for honeyeaters and native bees during the cooler months.

Q: What soils does the Lemon Scented Gum grow in?

Corymbia citriodora is highly adaptable and grows in clay, loam, sandy, and well-drained soils. Making it one of the most soil-tolerant large native trees in Australia. Good drainage is preferred; avoid persistently waterlogged positions.

Q: What pests affect Corymbia citriodora?

Common pests include caterpillars, leaf miners, scale, and thrips. These rarely cause serious long-term damage to a healthy established tree. Monitor new growth on young trees and treat severe infestations with an appropriate organic or targeted spray if needed.
