Family: Asteraceae

Dahlia ‘Café au Lait’ is an herbaceous plant native to Holland. ‘Café au Lait’ dahlias are highly prized by gardeners and florists alike for their stunning appearance. They make excellent additions to garden borders, cutting gardens, and floral arrangements. They are often grown outdoors in California and Oregon, however, pose little to no threat for naturalization because seed production may be limited or absent. This plant has not been documented as naturalized in any Hawaiian Islands to date.

High Risk Traits:

• Grows and could potentially spread in regions with tropical climates
  
• Other species may be weedy or invasive
  
• Unpalatable to deer and probably other browsing animals
  
• Reported to be toxic to animals
  
• May be toxic or cause skin irritation if handled
  
• Tolerates many soil types
  
• Tuberous herb
  
• Reproduces by vegetative division
  
• Dispersed through intentional cultivation

Low Risk Traits:

• An ornamental plant of hybrid origin, with no evidence of naturalization or invasiveness where cultivated
  
• Unarmed (no spines, thorns, or burrs)
  
• Grows best in high light environments (dense shade may inhibit spread)
  
• Seed production may be limited or absent
  
• Seeds, if produced, lack evident specialized dispersal structures and fall to the ground due to gravity
