About Prickly lettuce
Lactuca serriola, commonly known as Prickly Lettuce or Wild Lettuce, is an annual or biennial herbaceous plant belonging to the Asteraceae family. It is characterized by its lobed leaves with spines along the margins and on the underside of the central vein, and by its milky sap. As a ruderal plant, it can add a wild and natural touch to low-maintenance gardens or ecological restoration areas.
Native range
Europe, North Africa, and Western Asia
Care tips
Lactuca serriola is a very hardy and low-maintenance plant. It prefers full sun to partial shade and adapts to a wide range of soils, though it favors well-drained and not overly rich substrates. Watering should be moderate, allowing the soil to dry out between waterings, as it tolerates drought well. A common mistake is attempting to cultivate it in very fertile and moist soils, which can lead to excessive and less resilient growth.
