In this innovative and colorful work of early nonfiction from Caldecott Honor?winning author Lois Ehlert, little ones are introduced to facts about trees.

Ehlert blends bold graphics, vibrant colors, and precise details in her watercolor collage alongside found objects like seeds, fabric, wire, and roots.

A special glossary explains how roots absorb nutrients, what photosynthesis is, how sap circulates, how to make a bird treat, and other facts about trees. Children and adults will feel inspired to take a closer look at the nature in their own backyards.

Celebrate Earth Day, spring, and the basics of trees while improving color recognition with Lois Ehlert's Red Leaf, Yellow Leaf!

Lois Ehlert was the author-illustrator of many picture books, including Caldecott Honor?winning Color Zoo, Leaf Man, Pie in the Sky, In My World, Growing Vegetable Soup, Planting a Rainbow, and the best-selling Waiting for Wings.
