Botany of Desire

The human-plant relationship is explored via the stories of the apple, the tulip, marijuana and the potato. Included: how the apple came to be sweet; "tulip mania" in the Netherlands circa the 1630s, when tulips were traded for large sums of money; the history and physiology of marijuana; the genetically modified (and no longer available) New Leaf potato, which featured a microorganism that repelled potato beetles. Michael Pollan ("The Botany of Desire") hosts. Frances McDormand narrates.
