You may complain about them when they get lodged between your teeth, but in your heart you know how important seeds are, right? Without seeds, most of the plant world would not exist. And it's not just birds that eat them: see movies, popcorn.

The author, herself a broadcaster on NPR affiliate stations ("Cultivating Place"), visits with sketches from her research into the book.
