"Lettuce (Lactuca sativa) is a member of the Asteraceae family. Lettuce was cultivated as early as 4500 BC, in the Mediterranean region, for oil extracted from the seeds. Since then, production of the annual plant has spread worldwide. 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. capitata) 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. The primary product of greenhouse lettuce is the leaf which is produced in heads and is used mainly for salads. Pre-washed and pre-cut packaged salad mixes have become popular with consumers"--Page 1. Lettuce Diseases and pests Control Canada. Lettuce industry Canada. Greenhouse plants Canada. Canada.
