Family: Acanthaceae
High Risk Traits:
- Broad climate suitability (USDA Zones 9a-11)
- History of repeated introductions outside native range (e.g., California, Florida, Texas, Thailand, India, Micronesia)
- Shade tolerant
- Tolerates wide range of soil conditions (sand, loam, clay; acidic to slightly alkaline)
- Propagules likely dispersed unintentionally (e.g., via garden waste)
- Propagules dispersed intentionally as ornamental plant
- Tolerates mutilation / benefits from regrowth from roots
Low Risk Traits:
- No evidence of naturalization beyond native range
- No evidence of weediness (agricultural, environmental, or congeneric)
- No spines, thorns, or burrs
- No evidence of toxicity to animals or humans
- No evidence of prolific seed production (seed set infrequent in cultivation)
- No adaptations for wind, bird, animal, or gut dispersal (capsule with explosive dehiscence)
