Family: Araliaceae
Origin, Description & Uses
Trevesia palmata is a striking tropical tree native to the Himalayan foothills and Southeast Asia, ranging from Nepal through southern China to Indochina. It is prized for its bold, deeply lobed, palm-like leaves that can reach impressive sizes, giving gardens a lush, tropical appearance. Growing as a small to medium-sized tree, it produces clusters of small flowers followed by rounded fruits that attract birds and other wildlife in its native range. Because of its dramatic foliage and architectural form, Trevesia palmata is occasionally cultivated as an ornamental specimen in tropical and subtropical landscapes and botanical gardens.
Risks & Threats
Although Trevesia palmata is not currently known to be naturalized in the Hawaiian Islands, it possesses traits that are cause for concern, including the production of fleshy fruits that may be dispersed by birds and its ability to thrive in warm, moist environments. These characteristics could increase its potential to spread beyond cultivation under favorable conditions. Ongoing evaluation is needed to determine whether this species could impact Hawaii’s native ecosystems. Gardeners who choose to grow Trevesia palmata should monitor plants for unwanted seedlings and avoid planting it near natural areas until its invasive potential is better understood.
High Risk Traits:
- Produces sharp stem spines
- Broad climate suitability (wide elevational range: 250–2000 m)
- Native to tropical/subtropical Asia
- Shade-tolerant
- Tolerates loam, sand, and neutral to alkaline soils
- Produces viable seed
- Fleshy fruits dispersed by birds
- Host for mealybugs and spider mites
Low Risk Traits:
- Not naturalized outside native range
- Not a weed (garden, agricultural, or environmental)
- Young inflorescences are edible (no general human toxicity reported)
