Generally speaking double peonies are more fragrant than singles.  Pinks and whites tend to be more fragrant than the reds, but there are of course exceptions. 

     Peonies have been described as having an old rose scent, some report  no scent at all, some have reported a lemon scent and others describe a spicy scent.  Very little has been written on the subject of peony fragrance because it is so subjective.

      At our "Peony Show" we asked our guests to complete a fragrance survey.  The following peonies were found to be the most pleasantly fragrant to most people, Candy Heart, Edulis Superba, Evening Star, Festiva Maxima, La Perle,  Mrs. Franklin D. Roosevelt, Raspberry Sundae, Sarah Bernhardt, Solange, and White Cap.
