In Season: arugula, Bibb lettuce, Boston lettuce, mache, and mesclun are available year-round but thrive in the cooler weather of spring and fall.
What to Look For: Leaves should be bright and fresh looking. Choose crisp lettuces that are free of blemishes.
How to Store: Lettuce should be washed and thoroughly dried in a salad spinner to remove any excess moisture. Refrigerate washed-and-dried greens in an airtight plastic bag for three to five days.
