Family: Rubiaceae
High Risk Traits:
- Thrives in tropical climates
- Shade-tolerant
- Ecology and biology poorly understood. Unknown potential to exploit or become invasive in Hawaiian or other tropical island ecosystems
Low Risk Traits:
- Rare in cultivation, but no evidence of naturalization or weediness reported
- Unarmed (No spines, thorns or burrs)
- Landscaping and ornamental value
- Showy flowers
- Low seed viability, possibly due to lowered genetic diversity and inbreeding depression (would limit ability to escape via seed production and dispersal)
