Family: Lamiaceae

Origin, Description & Uses:
Salvia buchananii, commonly known as Buchanan’s sage, fuchsia sage, or purple autumn sage, is a perennial flowering plant native to a small region of northeastern Querétaro, Mexico. It is valued for its striking deep magenta to purple, tubular flowers and velvety green foliage, which give it strong ornamental appeal in gardens and landscapes. Growing best in warm subtropical climates, this sage attracts pollinators such as hummingbirds and butterflies and is often used in borders, cottage gardens, pollinator gardens, and container plantings. Its long flowering season and colorful blooms make it a favorite among gardeners seeking vibrant, low-maintenance plants.

Risks & Threats:
Salvia buchananii is considered a low-risk species and has not demonstrated invasive tendencies in tropical or subtropical regions where it is cultivated. It generally spreads slowly and is primarily propagated through intentional planting rather than natural dispersal. While any non-native plant should be monitored when introduced to new environments, there is little evidence that this species poses significant ecological threats to native habitats or biodiversity. With responsible cultivation and proper garden management, Buchanan’s sage can be enjoyed as an attractive ornamental plant with minimal environmental risk.

High Risk Traits:

• Elevation range exceeds 1000 m, but occurs at higher elevation in native range
  
• Grows in tropical climates
  
• Other Salvia species are invasive weeds
  
• May be unpalatable to animals
  
• Shade-tolerant
  
• Reproduces by seeds and vegetatively
  
• Intentionally dispersed by people
  
• Limited ecological information reduces accuracy of risk prediction

Low Risk Traits:

• No reports of invasiveness or naturalization
  
• Unarmed (no spines, thorns, or burrs)
  
• Non-toxic
  
• Ornamental value
