Lactuca sativa is an annual plant with leaves arranged in a rosette. At first, the leaves grow densely packed together. It is precisely this growth habit that is valued at harvest time. As soon as the plant begins to flower, the stem elongates; the lettuce “bolts” and forms a yellow flower head.

Today, there are several varieties of this type of lettuce. In addition to the well-known head lettuce, this group also includes romaine lettuce. In Switzerland, it is known by its original name, Lattich. Its elongated leaves are thicker and firmer than those of iceberg lettuce. They have a stronger flavor and, depending on the variety, a slightly nutty taste.

In the past, the leaves of romaine lettuce were tied together to keep the inner leaves light green and tender. This is also reflected in the name "Bindesalat" (tied lettuce). Modern varieties naturally form tightly packed leaves.
