Iceberg lettuce was grown in North America well over a hundred years ago. Its name probably dates back to the original mode of transport, when lettuces were covered with large blocks of ice to keep them cool throughout the journey. It was BEHR GemüseGarten that made iceberg lettuce popular in Germany in the 1980s. Today, iceberg is one of the most popular lettuces and virtually a staple in German kitchens.
