Family: Apocynaceae
High Risk Traits:
- Widely cultivated, increasing introduction risk.
- Seeds are wind-dispersed via a tuft of hairs (pappus).
- Toxic to humans and animals, reducing herbivory.
- Unpalatable to grazing animals.
Low Risk Traits:
- No record of naturalization or invasiveness anywhere.
- Not self-fertile; requires cross-pollination between two different plants.
- Requires specialist pollinators (e.g., hawk moths).
- Cannot spread vegetatively from fragments.
- Seeds are short-lived with no persistent soil seed bank.
- Cold-sensitive and frost-tender, limiting its range.
- Poor tolerance to mutilation; damaged plants are prone to fatal rot.
