Everywhere that Princess Daffodil walks, flowers bloom behind her. So it goes in The Magic Hill by A. A. Milne, (gorgeously illustrated by Isabel Bodor Brown.)
Perhaps like Princess Daffodil, flowers bloom behind us all... only they're not the sort of flowers that are visible to the eye.
This spring, carry wildflower seeds in your pockets to sprinkle here and there while walking the urban trails. You'll make the world a bit more colorful.
