Whitebox Tree: A Large Non-Native Eucalyptus for Spacious Landscapes

If you’ve got acres to spare and are looking for a fast-growing shade tree, the whitebox (Eucalyptus hemiphloia var. albens) might catch your eye. This towering eucalyptus variety, also known by its synonym Eucalyptus albens, brings that distinctive Australian flair to large landscapes – though it’s definitely not a tree for every garden!

What Exactly Is Whitebox?

Whitebox is a perennial tree species native to eastern Australia, specifically New South Wales and Queensland. As a true eucalyptus, it’s a woody plant with a single trunk that typically grows well beyond 13-16 feet in height – and we mean well beyond! This is a tree that means business when it comes to size.

Where You’ll Find It Growing

In the United States, whitebox has established itself in Hawaii, where it’s considered a non-native species that reproduces naturally in the wild. While it’s not originally from Hawaiian soil, it has adapted well to the island environment.

Should You Plant Whitebox in Your Garden?

Here’s where things get interesting – and where you need to think carefully about your space and goals.

Reasons you might want to plant whitebox:

  • Fast-growing shade tree for large properties
  • Drought tolerant once established
  • Distinctive aromatic foliage
  • Can serve as an effective windbreak
  • Eucalyptus flowers typically attract pollinators like bees

Reasons to think twice:

  • Requires enormous space – not suitable for typical residential lots
  • Non-native species that may not support local wildlife as effectively as native alternatives
  • Can become very large and potentially problematic if not properly sited
  • May drop branches and require maintenance

Growing Whitebox Successfully

If you’ve decided this tree fits your large-scale landscape vision, here’s how to help it thrive:

Location and Spacing: This tree needs serious room to grow. Plant it well away from buildings, power lines, and property boundaries. Think of it as needing its own zip code!

Growing Conditions: Whitebox performs best in full sun with well-draining soil. Like most eucalyptus species, it’s quite drought tolerant once its root system is established, but young trees will need regular watering to get started.

Climate Requirements: This tree is likely suitable for USDA hardiness zones 9-11, typical for eucalyptus species that have adapted to subtropical and tropical climates.

Planting Tips: Plant young trees in spring, water regularly during the first growing season, and then step back and watch it take off. Minimal fertilization is usually needed once established.

Consider Native Alternatives

While whitebox isn’t considered invasive, planting native species is always a great choice for supporting local ecosystems. If you’re looking for large shade trees, consider researching native options in your area that can provide similar benefits while supporting local wildlife and pollinators more effectively.

Remember, this is a tree that’s going to be around for decades and will dramatically change your landscape. Make sure you’re ready for that commitment – and that your neighbors are too!
