Family: Asphodelaceae

Kumara plicatilis (syn. Aloe plicatilis), commonly known as the fan aloe, is a striking succulent shrub native to the Western Cape of South Africa. This unique aloe gets its name from the way its gray-green, tongue-shaped leaves grow in opposite pairs, forming neat, fan-like arrangements along its branches. In spring, the plant produces clusters of tubular, orange-red flowers that attract pollinators such as birds and insects. Its sculptural shape and vibrant blooms make it a highly desirable ornamental plant in dryland gardens and landscapes.

In the Hawaiian Islands, fan aloe is only found in cultivation and has not shown signs of naturalizing. While it poses little to no invasive risk, its drought tolerance and ability to thrive in poor soils mean it should be monitored if widely planted. For now, it is considered a safe and attractive option for xeriscaping, container planting, and adding architectural interest to gardens without threatening native ecosystems.

High Risk Traits:

• Other Aloe species have become invasive
  
• Seedlings are Shade-tolerant
  
• Reproduces by seeds and vegetatively by fallen branches that root
  
• May exhibit low levels of self-compatibility
  
• Seeds dispersed by wind and intentionally by people
  
• Corky bark protects against fire

Low Risk Traits:

• No confirmed evidence of invasiveness or naturalization to date
  
• Almost unarmed leaves
  
• Non-toxic
  
• Ornamental
  
• Requires acidic soils
  
• Slow growth rate; reaches maturity in 6-8 years
  
• Does not form a persistent seed bank
  
• Limited seed production when populations occur at low densities
