Tonight on PBS: The Botany of Desire

Are you as excited as we are about the PBS premiere of "The Botany of Desire"? Based on Michael Pollan's best-selling book of the same name, the documentary examines the relationship between people and four plants: apples, tulips, marijuana, and potatoes. Click through for a preview video and highlights from the accompanying Web site.

Like the book, the documentary explores the theme of coevolution. While plants have satisfied our desires for sweetness (apples), beauty (tulips), intoxication (marijauna), and control (potatoes), we humans have been "domesticated" by plants to act much like bumblebees, spreading their particular genes around the world. The documentary looks engaging, thought-provoking, and beautiful as it takes us to the original apple orchards of Kazakhstan and the potato fields of Peru.

We're also big nerds for PBS program Web sites, and this one doesn't disappoint. It includes bonus videos like "How The Delicious Apple Got Its Name," an interactive feature on mind-altering plants (including coffee and tea), and a map where you can track the movement of plants across time and around the globe.

"The Botany of Desire" debuts on PBS on Wednesday, October 28.
