I live on a farm where we have a very old Lilac bush.   When it blossoms in the spring, I can smell them all over the back yard and it is one of my favorite fragrances.    Unfortunately, they only blossom for a few days!!   So, I always purchase a Large Lilac Blossom Jar candle when I can.  The fragrance of the candle lasts for a very long time and fills my large farmhouse with a glorious smell.   I love it!!
