Family: Arecaceae
Origin, Description & Uses
Pigafetta filaris (pigafetta palm, wanga palm) is a striking tropical palm native to the Maluku Islands and western to northern New Guinea. It is known for its extremely fast growth, tall slender trunk covered with dark spines, and large feathery fronds that create a dramatic tropical appearance. In suitable climates, this palm can rapidly reach impressive heights, making it popular as an ornamental landscape specimen in botanical gardens, resorts, and spacious tropical properties. Its bold form and rapid growth make it especially valued for creating an instant tropical effect.
Risks & Threats
Although Pigafetta filaris is not known to be naturalized in Hawaii, it does possess traits that are cause for concern. This species produces abundant seeds, grows quickly, and thrives in warm, wet tropical environments similar to those found in parts of the Hawaiian Islands. These characteristics may increase its potential to spread beyond cultivation if planted widely. In addition, the heavily spined trunk and leaf bases can create maintenance and safety concerns in landscaped areas. Ongoing evaluation is needed to determine whether this species could negatively impact Hawaii’s ecosystems or natural areas over time.
High Risk Traits:
- Thrives in tropical climates
- Began naturalizing on Tahiti, until control was initiated
- Fast-growing and disturbance adapted
- Spines along the bases of its leaves
- Tolerates many soil types
- Numerous, small seeds (for a palm) dispersed by birds and intentionally by people
- Limited ecological information makes accurate risk prediction difficult
Low Risk Traits:
- Not currently documented to be naturalized outside its native range
- Non-toxic
- Shade-intolerant
- Ornamental
- Dioecious
- Not reported to spread vegetatively
