Family: Bignoniaceae
High Risk Traits:
- Thrives in tropical climates
- Elevation range exceeds 1000 m
- Naturalized in Australia and possibly elsewhere
- Classified as an environmental weed in Australia
- Other Bignonia species have become weedy and invasive
- Climbing and smothering growth habit
- Tolerates many soil types
- Seeds, if produced, are adapted to wind-dispersal
- Can spread vegetatively, and from discarded garden waste
Low Risk Traits:
- Unarmed (no spines, thorns or burrs)
- Non-toxic
- May requires full sun
- Possibly self-incompatible
- Requires specialized pollinators
- Seed production may be limited or absent outside native range, minimizing risk of long-distance dispersal
