Salvia azurea (Blue Sage)
Family: Lamiaceae (Mint)
  
Salvia azurea is easily distinguished from other mints by its large bright blue flowers. Plants can grow to over four feet tall. Leaves are narrow and toothed. While the species is native to the Midwest and eastern U.S., it is unclear if it is native to Colorado. The pictured plants were growing at the Rocky Mountain Arsenal National Wildlife Refuge.
