Can plants hear? At first glance, this seems like a silly question. Plants don’t have ears, so of course they can’t hear. But wait—do organisms need ears to hear? What is hearing, anyway?

New gardening books seem to pop up as regularly as springtime dandelions. Most simply rehash what has been said before—perhaps with a new twist or better photos.

Instead, the author, Linda Chalker-Scott, explains the “why” behind the “how.”
