Peonies and antique roses are among my all time favorites, but I love all flowers; especially if they are fragrant. I'm very proud of my all white "moonlight" scented garden It appears to shimmer, especially under a full moon! Lilacs are another favorite. I read a quote once, "If memories had a fragrance, it would be a lilac!" And I love the smell of marigolds, when you crush the stem or the flower head. It takes me back to my childhood! I know some people hate the smell!
