Eucalyptus scoparia – Wallangarra White Gum

About Your New Eucalyptus scoparia – Wallangarra White Gum

Eucalyptus scoparia, the Wallangarra White Gum, is one of the best-behaved gums for a suburban block. The trunk is smooth and powdery white, shedding through the year to keep the colour clean, and it carries a broad open crown of narrow glossy leaves that hang with a slight weep.

It reaches around 8 to 12 metres tall and 5 to 10 metres wide, which is modest for a eucalypt. That size, plus the light dappled shade it throws rather than dense cover, is why it turns up so often in streetscapes, avenues and medium to large gardens where a bigger gum would be too much.

Small white flowers appear through spring and summer, followed by little oval gum nuts. The flowers bring nectar-feeding birds and insects, and the canopy gives shelter, so it earns its place as a habitat tree as well as a feature.

It comes from poor gravelly country on the Queensland and New South Wales border and is tougher than the white trunk suggests. It handles heat, dry conditions, compacted urban soil and most soil types, provided drainage is reasonable.

Frequently Asked Questions

About Eucalyptus scoparia

What is Eucalyptus scoparia?

An Australian native evergreen gum known as the Wallangarra White Gum, named for the Wallangarra district on the Queensland and New South Wales border where it occurs naturally. It is grown for its smooth powdery-white trunk, narrow glossy foliage and manageable size.

How big does it grow?

Around 8 to 12 metres tall and 5 to 10 metres wide, with a broad open crown. That is small for a eucalypt, which is the main reason it suits suburban blocks and street planting where most gums outgrow the space.

What makes the trunk white?

The bark is smooth and sheds through the year, peeling away to expose fresh powdery white to pale grey underneath. Because it renews itself the trunk stays clean and bright rather than weathering to dull grey, which is what makes it such a strong feature against dark foliage or a dark wall.

Is it suitable for a street tree?

Yes, it is one of the more commonly specified gums for streetscapes and avenues. The medium height, open crown and tolerance of compacted urban soil all suit it to the job, and the dappled shade it casts allows planting underneath.

When does it flower?

Small white flowers appear through spring and summer, followed by small oval seed capsules. The flowers are a nectar source for honeyeaters, lorikeets and native insects.

How much shade does it give?

Light dappled shade rather than dense cover, because of the narrow leaves and open crown. That is an advantage in a garden, as lawn and understorey planting will still grow beneath it, unlike under a heavily shading tree.

What soil and conditions does it need?

It grows naturally on poor gravelly soils, so it is undemanding and copes with most soil types including compacted urban ground. Full sun and reasonable drainage are what it wants. It handles heat and dry conditions well once established.

How do I care for it?

Water deeply through the first two summers to establish, then only in extended dry spells. Use a low-phosphorus native fertiliser, as eucalypts resent high-phosphorus blends. Formative pruning in the first few years sets a good single leader and clear trunk. Avoid heavy pruning of established trees.
