Family: Myrtaceae
High Risk Traits:
- Able to grow, and potentially spread, in regions with subtropical climates
- Other Callistemon species reported to be naturalized
- Tolerates many soil types
- Reproduces by numerous, tiny seeds
- Seeds may be dispersed for short distances by wind and water
- Serotinous seeds retained on plants, may form a persistent “canopy seed bank”
- Able to resprout after cutting and fires
Low Risk Traits:
- No reports of invasiveness or naturalization in Hawaii or elsewhere in the world
- Unarmed (no spines, thorns, or burrs)
- Non-toxic
- Serotinous seeds unlikely to be accidentally dispersed
