• Elevation range exceeds 1000 m, demonstrating environmental versatility
  
• Thrives in tropical climates
  
• Naturalized on Hawaii island (Hawaiian Islands), and in several other tropical locations
  
• An environmental weed in La Reunion
  
• Other Strobilanthes species are invasive
  
• Shade tolerant
