Trees Worth Knowing

One day the twigs are sealed in winter’s sleep; soon, while you watch a single shoot, the bare tree has clothed itself in summer.

In this early-twentieth-century guide to North American trees, Julia Ellen Rogers asks readers to look closely at the familiar trees around them—in yards, parks, and woods. A bud, she shows, is a whole shoot waiting under its winter scales; the leaf that unfolds becomes a sunlit laboratory, turning air, water, and minerals into the food that builds the tree. With wonder and scientific detail, Rogers traces the hidden work behind each green canopy and invites us to see trees not as scenery but as living, industrious beings. What else is happening in the leaves above your head?
