Family: Bignoniaceae
High Risk Traits:
- Thrives and spreads in regions with tropical climates
- Naturalized in Queensland, Australia (but no evidence in the Hawaiian Islands to date)
- Unconfirmed report that plant may be an allergen
- Tolerates many soil types
- Reproduces by seeds
- Self-compatible
- Fast growth rate
- Seeds dispersed by wind and through intentional cultivation
- Seeds may form a persistent seed bank (up to 4 years)
- Tolerates heavy grazing, mowing and fire
Low Risk Traits:
- No reports of negative impacts where grown
- Unarmed (no spines, thorns, or burrs)
- Thrives in full sun and high light environments (dense shade may inhibit spread)
- Seeds lose viability after 150 days of storage (unlikely to form a persistent seed bank)
