The Botany of Desire explores the natural history of four plants - the apple, the tulip, marijuana, and the potato - and the corresponding human desires- sweetness, beauty, intoxication and controlling nature - that link their destinies to our own. This two-hour documentary begins in Michael Pollan's garden, and roams the world, from the potato fields of Idaho and Peru to the apple orchards of New England, from a medical marijuana hot house to the tulip markets of Amsterdam.
