Family: Asphodelaceae

Aloe ‘Hercules’, commonly known as Hercules aloe, is a striking hybrid between Aloe barberae and Aloe dichotoma. This fast-growing tree aloe is prized as an ornamental for its massive size, sculptural form, and drought tolerance. Capable of reaching impressive heights with a stout trunk and branching canopy of spiky leaves, it makes a dramatic focal point in landscapes and is well-suited to dry, sunny areas. Its resilience in hot climates and low water requirements add to its appeal as a hardy landscaping plant.

In the Hawaiian Islands, Aloe ‘Hercules’ is only found in cultivation and has not been observed naturalizing. While it does not currently pose a threat to native ecosystems, it should be planted responsibly to prevent accidental spread in the future. Its large size and tough growth habit may make removal challenging if unwanted, so careful consideration of planting location is advised. With proper management, Hercules aloe can be an impressive and sustainable addition to gardens without negative ecological impacts.

High Risk Traits:

• Able to grow in tropical climates
  
• Other Aloe species have become invasive
  
• May be able to reproduce vegetatively
  
• Seeds, if produced, may be wind-dispersed
  
• Limited ecological information reduces accuracy of risk prediction

Low Risk Traits:

• No reports of invasiveness or naturalization
  
• Unarmed (no spines, thorns or burrs)
  
• Ornamental
  
• A hybrid that may not produce seeds (unclear)
  
• Requires birds for pollination
  
• Limited or absence seed production reduces risk of dispersal
