Corymbia maculata (Spotted Gum)

Corymbia maculata, commonly known as Spotted Gum, is a tall and elegant Australian native tree valued for its distinctive spotted trunk, fragrant flowers, and strong timber. Widely used in landscaping and forestry, it is an excellent choice for large gardens, parks, and open spaces.

Originally native to coastal and foothill regions of southern New South Wales, Spotted Gum is a hardy species that performs well in sunny locations and well-drained soils.

Identifying the Spotted Gum

One of the easiest ways to recognise Corymbia maculata is by its smooth, dimpled trunk. The bark ranges from white to pale cream and is marked with distinctive grey, pink, or brown “spots”, giving the tree its common name.

Corymbia maculata Quick Facts

Common Name	Spotted Gum
Height	15–40 m (sometimes taller)
Spread	Up to 10 m
Growth Rate	Medium

Spotted Gum Trunk - Corymbia maculata — Spotted Gum Trunk

Key Identification Features

Trunk: Smooth, cream to white with grey or pink spots
Foliage: Long, narrow, deep green leaves
Flowers: Masses of small white flowers from late summer through winter
Height: Typically 15–40 metres, sometimes taller in ideal conditions

The flowers are fragrant and highly attractive to bees, producing honey that is considered particularly high quality.

Corymbia vs Eucalyptus

Spotted Gum was once classified within the Eucalyptus genus, but taxonomic changes moved a number of species into the Corymbia genus.

Today, the genus includes around 100 species, many of which are sometimes referred to as “Bloodwoods.”

While similar to eucalypts in appearance and growth habit, Corymbia species are now recognised as a distinct botanical group.

Growing Corymbia maculata

Spotted Gum is a strong growing tree that becomes very tall at maturity. It is best suited to large landscapes or open spaces where it has room to develop.

Once established it is reasonably drought tolerant, although young trees benefit from protection during their early years.

Best Growing Conditions

Position

Full sun is ideal
Will tolerate light shade in open areas or between buildings

Soil

Well-drained soil is essential
Many Corymbia species dislike waterlogged ground

Watering

Moderate watering while establishing
Drought tolerant once mature

Frost

Young plants may require protection from heavy frost

Planting and Establishment

Spotted Gum is widely available from wholesale and retail nurseries, typically sold as:

Tubestock
Advanced young trees
Small specimen trees

Planting Tips

Plant from late summer through early spring
Protect young trees from grazing animals
Provide extra watering during the first summer
Mulch well to retain soil moisture

Landscaping Uses

Because of its size and striking bark, Corymbia maculata works best as a feature or shade tree in large spaces.

Ideal Uses

Feature tree in large gardens
Shade tree for parks and open landscapes
Street tree in suitable urban environments
Native garden plantings

The species is also known for strong branch structure, meaning it tends to retain limbs better than some other eucalypt relatives.

A variegated foliage form is occasionally available through specialist nurseries.

Landscape Size Warning

Due to its mature size, Spotted Gum is not recommended for small suburban gardens.

Timber Uses

Spotted Gum is also a highly valued timber species. The wood is durable, dense, and attractive, making it popular for:

Outdoor decking
Flooring
Furniture
Structural timber

Propagation

Corymbia maculata is easily propagated from seed, making it suitable for nursery production and revegetation projects.
