History of Lettuce Month

The ancient Egyptians first cultivated lettuce. They modified it from a plant whose seeds were a source of oil. The first documentation of lettuce farming dates to ancient Egypt over 6,000 years ago. Old Egyptian tomb paintings depicted different varieties of lettuce. The Egyptians taught the Greeks how to grow lettuce. They ate it as a salad before meals to help digestion and used it medicinally as a sedative. They continued to modify it for tastier leaves for salads. Lettuce became associated with sexual potency when it reached the Romans, who came to believe it could enhance stamina.

The vegetable traveled to Europe and China with the Romans. It was already well-known in Europe by the 1400s, with more varieties appearing. Some people speculated that Christopher Columbus brought lettuce to America on his 1494 voyage. However, it was John Winthrop Jr. who brought lettuce seeds to America from England in the 1600s.

Lettuce Month, also known as National Salad Month, started in 1992 through the efforts of the Association for Dressing and Sauces. A holiday to celebrate all things lettuce, health benefits, and tastiness.

The Outredgeous red Romaine lettuce was grown and eaten in space by astronauts on the International Space Station (I.S.S.) in 2015. Their garden was a Veggie chamber with the necessary illumination and rooted pillows for crop survival.
