Family: Crassulaceae
High Risk Traits:
- Able to grow in tropical climates
- Possibly naturalizing on Oahu, Hawaiian Islands (confirmation needed); naturalized in New Zealand
- Other Crassula species have become invasive
- Toxic to dogs, cats and potentially other animals; possibly toxic to people
- Shade-tolerant, but prefers full sun
- Forms dense populations in native range
- Reproduces by seeds and by vegetative fragments (one leaf able to form a new plant)
- Seeds dispersed by wind and intentionally by people
- Vegetative fragments can be dispersed as garden refuse
- Able to resprout after pruning or cutting
Low Risk Traits:
- Unarmed (no spines, thorns or burrs)
- Ornamental
- Possibly self-incompatible (which may limit seed production)
