They say that the sense most closely linked to memory is scent. Then for me, lilacs above all other flowers most closely remind me of my mom :) I'm fortunate to have the beautiful lilacs that she planted many years ago still blooming in my spring garden.
Every year without fail, their beauty and uniquely graceful fragrance surround my home, reminding me of my mom ~ working in her garden. She passed away when I was a teenager after a long battle with cancer. The return each spring of her lilacs is like a sweet reminder of her. I proudly explain to my son that they're his grandma's lilacs, as he buries his nose in the blossoms. And he smiles and says, "I can almost smell her, Mommy...so beautiful." :)
