Are both Emilia and Saxifraga types of plants?
Saxifraga Saxifraga is the largest genus in the family Saxifragaceae, containing about 440 species of holarctic perennial plants, known as saxifrages or rockfoils. The Latin word "saxifraga" means literally "stone-breaker", from Latin "saxum " ("rock" or "stone") + "frangere " ("to break"). It is usually thought to indicate a medicinal use for treatment of urinary calculi (known as kidney stones), rather than breaking rocks apart.
Achillea ageratum Achillea ageratum, also known as sweet yarrow, sweet-Nancy, or sweet maudlin, is a flowering plant in the sunflower family, native to southern Europe (Spain, Portugal, France, Italy, Greece, Balkans). It is cultivated in many places for its pleasant fragrance and sparingly naturalized in a few places outside its native range.
