Edible lamb's lettuce (Valerianella locusta)
It is a plant from the valerian family ( Valerianaceae), growing in the wild; it began to be cultivated only in the late Middle Ages. Lamb's lettuce should be grown in any garden due to the relatively high frost resistance of the leaves, making it a valuable source of vitamins during winter and early spring. Because it is a typical long-day plant, it is not sown until August or early September, directly on projecting beds or in rows 10-15 cm apart. The seeds should be lightly tapped or covered with a thin layer of earth.

In September, the seeds can also be sown in an inspection covered by a window. This guarantees fast and even plant development.
