Lettuce, like all green salads, belongs to leafy vegetables.  Even the ancient Romans appreciated its slightly sweet, crunchy leaves, which explains the reference to this salad as “Romaine Lettuce”.

Lettuce has rounded, elongated, green outer leaves. The inner leaves are tender because they get little sunlight and hence, have a pale golden colour. To enhance this in the past, young lettuce plants were tied together. However, more recent lettuce varieties are bred to grow in a tight form, so it is no longer necessary to tie the plants. The shape of lettuce heads range from round to oval. Romaine lettuce has a longer shelf life than head lettuce due to its stronger leaves. It can be prepared raw as a salad or steamed as a vegetable

Season: From May to September
