About Field milk thistle
Sonchus arvensis, commonly known as perennial sow-thistle, is a perennial herbaceous plant from the Asteraceae family, distinguished by its hollow stems and bright yellow, dandelion-like flowers. While often considered a weed in agricultural fields, its blossoms can add a wild and rustic touch to naturalistic gardens or meadows. It is a robust and adaptable plant capable of thriving in various environments.

Europe and temperate Asia
Care tips
This plant prefers full sun to partial shade and is highly tolerant of various soil types, though it thrives best in well-drained, nutrient-rich soils. It requires moderate watering, allowing the top layer of the substrate to dry out between waterings, and is quite drought-resistant once established. A common mistake is underestimating its vigor and spreading capacity, as it can rapidly propagate through rhizomes and seeds. For effective control in ornamental gardens, regular manual removal of seedlings and management of seed dispersal are recommended.
