Quick facts

About Wild lettuce

Lactuca virosa, commonly known as Wild Lettuce or Poisonous Lettuce, is a biennial herbaceous plant that can reach heights of up to 1.5 meters. It is characterized by its bluish-green lobed leaves and pale yellow flowers grouped in inflorescences. It is an interesting plant for naturalistic gardens or for those interested in plants with medicinal and ethnobotanical properties, although it should be handled with caution due to its milky sap containing lactucarium.

Native range

Europe, Western Asia, and North Africa

Care tips

It prefers full sun to partial shade and well-drained soils, although it tolerates a variety of soil conditions. Watering should be moderate, allowing the substrate to dry slightly between waterings, as it is quite drought-tolerant once established. Avoid excessive moisture, as it can lead to fungal diseases. A common mistake is to confuse it with other lettuce species and consume it without knowledge of its properties, which is not advisable.
