Lettuce is the common name for a number of related plants that grow in “heads”.
Varieties of lettuce include iceberg, romaine, red leaf, and butterhead. Because their growing seasons peak at different times of year, there's always a plenitude of this salad staple.
Because lettuce is on the Environmental Working Group's list of the most chemically contaminated foods - the Dirty Dozen - be sure to always pick organic.
