Family: Hamamelidaceae

High Risk Traits:

• Grows in temperate to subtropical climates
  
• Naturalized in Alabama, and Arkansas (continental US), but no evidence in the Hawaiian Islands to date
  
• Tolerates many soil types
  
• Reproduces by seeds
  
• Self-compatible
  
• Seeds dispersed ballistically from dehiscent capsules and intentionally by people
  
• Tolerates severe pruning

Low Risk Traits:

• No reports of invasiveness or detrimental impacts outside introduced range
  
• Unarmed (no spines, thorns, or burrs)
  
• Not reported to spread vegetatively
  
• Reaches maturity in 5-8 years
  
• Without human assistance, ballistic dispersal may limit potential spread to vicinity of cultivated plants
