This collection of haiku is a 3.5 for me. Complemented by splendid illustrations created in gouache and that fill the pages will intense depictions of trees and their various parts, this book makes a good choice for a science lesson on the topic, blending poetry and science. As teachers often do, I'm always on the hunt for children's books that can function in several ways, which makes this one filled with curricular possibilities. It's clear that the author loves her subject matter and has spent quite some time researching trees. The poems discuss the origins of trees as well as seeds and even look inside a tree in insightful fashion and not just on the outside; for instance, xylem is described as "tree elevators" (unpaged), while phloem is tagged as "hidden waterways" (unpaged). The poems are divided into ten sections: "In Times Long Past," "What's in a Name?" "Seeds," "On the Outside," "Peeking Inside," "Treetops," "Leaf Laboratories," "Good Neighbors," "Wild Forests," and "Urban Forests." Each haiku works well in revealing essential elements of the topics, and the abundant back matter expands on each section. So much information is provided in that part of the book that readers may feel a bit overwhelmed, but all of it is interesting and noteworthy. There's even a Glossary. It's hard to imagine anyone reading these poems and the additional information and not coming away with an entirely new perspective on trees. Surely, there will be many science and English language arts teachers who will add this one to their collection.
