Family: Myrtaceae
High Risk Traits:
- Naturalized in multiple introduced regions (Hawaii, Fiji, St. Croix) and has a long history of intentional human dispersal
- Congeneric relative (S. cumini) is a highly invasive environmental weed
- Shade-tolerant and adaptable to a wide range of soil types (sand to clay)
- Produces viable, readily germinating seeds that survive gut passage and are dispersed by birds and fruit bats
Low Risk Traits:
- Not weedy, or considered an agricultural, garden, or environmental weed
- Lacks physical defenses (no spines, thorns, burrs) and does not form dense thickets or climb
- Non-toxic to humans and animals; not allelopathic and not a host for major pests or pathogens
- Does not create fire hazards, reproduce vegetatively, or hybridize naturally
- Seeds are large, not adapted for wind, water, or external animal dispersal, and do not form a persistent seed bank (viability is short)
- Long generation time (7–8 years to flower) and sensitive to heavy pruning and fire
