Family: Fabaceae
High Risk Traits:
- Adapted to tropical climates
- Broad climate suitability and elevation range
- Naturalized in Argentina (but no evidence in the Hawaiian Islands to date)
- A pioneer tree that could establish in open, disturbed habitats
- Other Senna species are invasive weeds
- Shade tolerant
- Tolerates many soil types
- Reproduces by seeds
- Self-fertile (autogamous)
- Fast growth rate (but time to maturity unknown)
- Seeds dispersed by autochory (self-dispersal), by mammals (internally), by ants (externally), potentially by water and through intentional cultivation
- Seeds may form a persistent seed bank
Low Risk Traits:
- Despite naturalization, negative impacts have not been reported to date
- Unarmed (no spines, thorns, or burrs)
- Non-toxic
- Grows best in high light environments (dense shade may inhibit spread)
