Family: Asparagaceae
High Risk Traits:
- Thrives in tropical climates
- Naturalized elsewhere (but not reported in the Hawaiian Islands)
- Regarded as an environmental weed in the Canary Islands, South Africa and possibly elsewhere
- Other Agave species have become invasive
- Leaves with marginal prickles and terminal spine
- Sap may be an irritant or toxic to both animals and people
- Tolerates many soil types
- Forms dense stands that can exclude other vegetation and people
- Seeds dispersed by wind, water and intentionally by people
- Hybridizes with other Agave species
- Self-compatible
- Suckers from the base (able to spread vegetatively)
Low Risk Traits:
- Provides fodder for livestock (palatable despite reports of toxicity)
- Ornamental
- May not be able to invade shadier areas
- Reaches sexual maturity after decades of growth (but able to spread vegetatively at an earlier age)
- Herbicides provide effective control
- Mechanical removal and hot fires may also control plants
