Applebox Tree: A Hardy Australian Native for Warmer Climates
If you’re looking for a drought-tolerant shade tree that can handle tough conditions, you might have come across the applebox tree (Eucalyptus bridgesiana). This Australian native has found its way into Hawaiian landscapes and other warm climate gardens, bringing a touch of the Outback to backyards around the world.
What is an Applebox Tree?
The applebox is a medium to large eucalyptus tree that’s built to last. As a perennial woody plant, it typically grows with a single trunk and can reach impressive heights of 50-80 feet tall with a spread of 30-50 feet wide. Don’t let the size intimidate you though – under certain conditions, it can develop a more manageable multi-stemmed form or stay shorter than its typical towering height.
What sets this eucalyptus apart is its distinctive rough, fibrous bark that gives it character and visual interest. The narrow, blue-green leaves flutter in the breeze, and when the tree blooms, it produces clusters of white to cream-colored flowers that are quite the sight to behold.
Where Does Applebox Come From?
Originally hailing from southeastern Australia – particularly New South Wales and Victoria – the applebox tree has adapted well to life beyond its native borders. In the United States, you’ll find it growing in Hawaii, where it has established itself as a non-native species that reproduces naturally in the wild.
Should You Plant an Applebox Tree?
The decision to plant an applebox really depends on your specific situation and goals. Here are some things to consider:
Reasons you might love it:
- Incredibly drought tolerant once established
- Provides excellent shade with its broad canopy
- Attracts pollinators like bees when in bloom
- Offers shelter and food for various bird species
- Handles coastal conditions and wind exposure well
- Low maintenance once mature
Reasons you might want to reconsider:
- Requires significant space due to its large size
- Can be messy with dropping bark and leaves
- May not be the best choice for small residential lots
- As a non-native species, it doesn’t support local ecosystems as well as native alternatives
Native Alternatives to Consider
If you’re in Hawaii or other warm climate zones, consider exploring native tree options that provide similar benefits while supporting local wildlife and ecosystems. Native species are typically better adapted to local conditions and require fewer resources to maintain.
Growing Conditions and Care
If you decide to plant an applebox tree, you’ll be happy to know it’s relatively low-maintenance. This hardy tree thrives in USDA hardiness zones 9-11, making it suitable for consistently warm climates.
Ideal growing conditions:
- Full sun exposure (at least 6-8 hours daily)
- Well-draining soil – it doesn’t like wet feet
- Space to grow – remember that 30-50 foot spread!
- Protection from strong winds when young
Planting and Care Tips
When to plant: Spring is your best bet, giving the tree a full growing season to establish before any cooler weather arrives.
Planting process: Dig a hole twice as wide as the root ball but no deeper. The top of the root ball should be level with the surrounding soil. Backfill with native soil and water thoroughly.
First-year care: Water regularly during the first year to help establish a strong root system. After that, the tree becomes remarkably drought tolerant.
Ongoing maintenance: Minimal pruning is needed – just remove dead or damaged branches. The tree will naturally develop its characteristic shape.
The Bottom Line
The applebox tree can be a valuable addition to large properties in warm climates, especially where drought tolerance and low maintenance are priorities. However, before planting any non-native species, consider whether native alternatives might better serve your landscape goals while supporting local ecosystems. If you do choose to plant an applebox, give it plenty of room to grow and enjoy the shade and character it will bring to your landscape for decades to come.
