Loved this book! The illustrations were delightful! The text is crisp and held the attention of my children ages 3 to 8. My oldest two children then went on to read it a few more times by themselves. We used this as a text for a unit on...yes, trees. There is SO much to pull from the book: science, history, geography, gardening, use of public spaces, as well as themes of determination and vision, goal setting, etc. After reading it, I pulled up photos of the garden in San Diego, as well as some before and after photos of the garden. We all found this part, the actual transformation displayed in historical photos, fascinating. This is a sweetly researched, planned, written and designed book. Kudos to the author and illustrator! Definitely a book to have in one's library.
