Deviltree: A Tropical Shade Giant for Warm Climate Gardens
If you’re looking for a substantial shade tree for your tropical or subtropical garden, the deviltree (Alstonia macrophylla) might catch your eye. This impressive tree brings a touch of Southeast Asian elegance to landscapes, though it’s definitely not for every garden or climate.
What Is Deviltree?
Deviltree is a large, perennial tree that typically grows over 13-16 feet tall with a single trunk. Originally from Southeast Asia, this non-native species has established itself in parts of Florida and Hawaii, where it reproduces naturally without human assistance.
Where Does It Grow?
In the United States, you’ll find deviltree growing in Florida and Hawaii. As a tropical species, it’s only suited for USDA hardiness zones 10-12, meaning it needs consistently warm temperatures year-round to thrive.
Why You Might (Or Might Not) Want to Plant Deviltree
Reasons to consider it:
- Creates excellent shade with its broad canopy
- Features attractive, glossy green leaves arranged in distinctive whorls
- Produces fragrant white flowers that attract pollinators like bees and moths
- Low maintenance once established
- Makes an impressive specimen tree in large landscapes
Reasons to think twice:
- Only suitable for tropical and subtropical climates (zones 10-12)
- It’s a non-native species that can self-seed in the landscape
- Requires significant space due to its large size
- May not provide the same ecological benefits as native alternatives
Native Alternatives to Consider
Before planting deviltree, consider these native shade trees that offer similar benefits while supporting local ecosystems:
- Live Oak (Quercus virginiana) – for Florida
- Kukui (Aleurites moluccanus) – for Hawaii
- Bald Cypress (Taxodium distichum) – for Florida wetland areas
Growing Deviltree Successfully
Ideal Growing Conditions
Deviltree thrives in:
- Full sun to partial shade locations
- Well-draining soil (though it’s adaptable to various soil types)
- Consistently warm, frost-free climates
- Areas with regular rainfall or supplemental watering
Planting and Care Tips
Planting: Choose a location with plenty of room for growth, as this tree can become quite large. Plant in spring after any danger of cool weather has passed.
Watering: Young trees need regular watering to establish strong root systems. Once mature, deviltree is relatively drought-tolerant but performs best with consistent moisture.
Maintenance: This is generally a low-maintenance tree. Minimal pruning is needed – just remove any dead, damaged, or crossing branches. The tree naturally develops an attractive shape.
Special considerations: The tree produces a milky sap, so wear gloves when handling cut branches or leaves.
Wildlife and Pollinator Benefits
Deviltree’s fragrant white flowers attract various pollinators, including bees, moths, and other insects. While it may provide some habitat value, native trees typically offer greater benefits to local wildlife and ecosystems.
Is Deviltree Right for Your Garden?
Deviltree can be an attractive addition to large tropical and subtropical landscapes, especially if you need a substantial shade tree. However, as a non-native species, it’s worth considering native alternatives that provide similar benefits while better supporting your local ecosystem. If you do choose to plant deviltree, ensure you have adequate space and the right climate conditions for this impressive tree to thrive.
