Weeds Find a Way by Cindy Jenson-Elliot, illustrations by Carolyn Fisher is lovely and weird. "Loathe them or love them..." is says on the inside front cover and I agree that most people love them or hate. I love them, and this book.
Teachers and parents will love this book and the study guide here.
The illustrations were made with mixed media and digital collage. The weeds fairly come alive and you think you can pick that dandelion fluff, feel the wiggling roots, and pick that wildflower.
I'll use this title this summer when we study plants. I'll suggest it to parents and teachers of preschoolers to 2nd graders.
There is more information in the back about each weed represented.
