- Flowers can be white, pink or red
- Forms a lignotuber at the base
- Leaves used for eucalyptus oil production
- Six subspecies recognised across south-eastern Australia
- 'Euky Dwarf' is a compact garden form
What does Yellow gum look like?
Yellow gum grows 10 to 30 metres tall and forms a lignotuber at its base. Its bark is mostly smooth in white, yellow or bluish-grey tones, with rough fibrous patches near the trunk’s foot. Adult leaves are lance-shaped, glossy green on both sides, and taper to a short stalk. Flowers appear in threes, opening to white, pink or red blooms. The fruit is a woody capsule, cylindrical to nearly round.
Where does Yellow gum come from?
This species is found only in south-eastern mainland Australia. It was first described in 1855 by Ferdinand von Mueller. The name combines Greek words for 'white' and 'wood'. Six subspecies are recognised, each adapted to different local soils and climates across Victoria, South Australia and far western New South Wales.
When and how Yellow gum blooms
Yellow gum flowers in most months of the year. It grows in varied habitats, from coastal zones to inland ranges. Some forms thrive on skeletal soils, others in drier plains. In cultivation, selected types like 'Rosea' and 'Euky Dwarf' are planted in gardens and streets for their compact size and showy winter blooms.
How Yellow gum is used
The leaves yield cineole-rich eucalyptus oil when distilled. Certain subspecies are valued as ornamental trees in parks and home gardens, especially where space is limited. 'Euky Dwarf' reaches just 5–6 metres and is used in urban landscaping.
Kinds of Yellow gum
Subspecies include bellarinensis, known only from the Bellarine Peninsula, and connata, which grows in the Brisbane Ranges with fused juvenile leaves. Subspecies pruinosa has waxy foliage and white flowers, while megalocarpa, sold as 'Rosea', has broad leaves, red flowers and large fruit.
What Yellow gum means
Though not tied to specific festivals or faiths, yellow gum is appreciated in Australian horticulture. Its oil has traditional uses, and its hard wood gives it the name 'white ironbark'. Some subspecies are restricted to small geographic areas, making them of conservation interest.
