Family: Bignoniaceae
High Risk Traits:
- Naturalized in the Hawaiian Islands (Maui, Kauai, Hawaii), New Zealand, and possibly elsewhere
- Thrives in sub-tropical and Mediterranean climates
- Cultivated in a range of elevations from 0-3000 m
- Garden and landscaping weed (nuisance plant smothers surrounding vegetation)
- Tolerates many soil conditions (and potentially able to exploit many different habitat types)
- Climbing and smothering growth habit
- Spread by wind-dispersed seeds, vegetatively and by garden waste (cuttings that can root)
- Tolerates and resprouts after heavy pruning and cutting
Low Risk Traits:
- Unarmed (no spines, thorns or burrs)
- Non-toxic
- Ornamental value (showy flowers)
- Limited seed production in cultivated settings
- Herbicides may provide effective control
