Legend has it that Saint Patrick drove all the snakes out of Ireland, but modern science confirms the slithering reptiles never actually lived there post-Ice Age. So, what exactly did the patron saint banish?

It is a bit of ancient PR that stuck, turning a religious holiday into a global celebration of all things green. As you celebrate the Emerald Isle this week, take a moment to appreciate the power of a good story—or perhaps just enjoy the coincidence that your favorite herb fits the color scheme perfectly.
