Is cooking sage and salvia farinacea the same thing?

No, cooking sage and Salvia farinacea are not the same thing. Cooking sage, or Salvia officinalis, is a culinary herb commonly used for flavoring dishes. Salvia farinacea, on the other hand, is an ornamental plant known for its attractive blue flowers and is not typically used for culinary purposes.
