Sommaire en anglais
Lettuce (Lactuca sativa), is a member of the Asteraceae. Lettuce was cultivated as early as 4500 BC in the Mediterranean region for the oil extracted from the seeds. Since then, production of the annual plant has spread world-wide. Today, lettuce is grown almost exclusively for the fresh market. It is used in salads, sandwiches and as a garnish. Lettuce can be split into two main groups: head lettuce (Lactuca sativa var. captain), which includes iceberg, crisphead and butterhead lettuce and leaf lettuce (L. sativa var. longifolia and L. sativa var. crispa), which includes romaine, greenleaf, and redleaf lettuce. Only butterhead lettuce, also known as Boston or Bibb lettuce (L. sativa var. capitata) is grown in greenhouses Prior and Cortina are the most common cultivars.
