Family: Zingiberaceae
Origin, Description & Uses:
Etlingera littoralis, commonly known as earth ginger or golden star, is a tropical plant native to Southeast Asia, including regions of Indonesia and nearby islands. It is a member of the ginger family (Zingiberaceae) and is valued for its striking ornamental qualities. This species produces lush, leafy shoots and distinctive ground-level flowers with star-like shapes and warm golden to orange tones. Its bold foliage and unusual blooms make it an attractive addition to tropical gardens and landscape plantings. Like many gingers, it thrives in warm, humid environments with partial shade and well-drained soils, and is primarily cultivated for decorative purposes rather than for culinary or medicinal use.
Risks & Threats:
Etlingera littoralis is considered a low-risk species, with no significant evidence of invasiveness or widespread naturalization. It does not appear to spread aggressively or outcompete native vegetation under typical growing conditions. While it may slowly expand through rhizomes, its growth is generally manageable in cultivated settings. As with most non-native plants, responsible planting and garden management are encouraged to prevent unintended spread, but overall, this species poses minimal threat to Hawaiʻi’s ecosystems.
High Risk Traits:
- Elevation range exceeds 1000 m in tropics
- Thrives in tropical climates
- Described as weedy in gardens or landscape settings by some growers
- Shade-tolerant
- Spread by rhizomes and seeds
- Seeds and propagules possibly dispersed by rodents and intentionally by people
- Spreads vegetatively
- Able to resprout after cutting
- Limited ecological information makes accurate risk prediction difficult
Low Risk Traits:
- No reports of invasiveness or negative impacts
- Unarmed (no spines, thorns or burrs)
- Non-toxic
- Ornamental
- Requires specialized bee pollinators (may limit seed set outside native range)
