High Risk Traits:
- An artificial hybrid of ambiguous taxonomy; reliability of cited sources uncertain.
- Able to grow, and potentially spread, in regions with tropical climates
- Species of Senecio, the genus in which the putative parent species of this hybrid were once classified, have become invasive weeds
- Reported to be toxic to cats, dogs, and mildly toxic to people if ingested
- Reported to reproduce by seeds and vegetatively by cuttings and rooting at nodes
- Limited reliable information on the biology and ecology of this hybrid reduces the accuracy of risk prediction
Low Risk Traits:
- A popular ornamental plant with no reports of naturalization or invasiveness elsewhere, but unclear how frequently this plant is grown outdoors
- Unarmed (no spines, thorns, or burrs)
- Most websites describe vegetative propagation of this hybrid, suggesting seed production may be limited or absent
