About Slender sowthistle
Sonchus tenerrimus, commonly known as slender sowthistle, is an annual or biennial herbaceous plant belonging to the Asteraceae family, characterized by its deeply lobed leaves and small, dandelion-like yellow flowers. It grows wild in Mediterranean climates, forming loose, ethereal clumps. It is ideal for naturalistic gardens, rock gardens, or as a ground cover in areas where a wild and low-maintenance look is desired.
Native range
Mediterranean region of Europe and North Africa, extending to Southwest Asia.
Care tips
This species prefers full sun to light partial shade and tolerates poor, well-drained soils, including sandy or rocky ones, without much need for fertilization. It is drought-tolerant once established, so watering should be moderate, allowing the substrate to dry out completely between waterings. Avoid waterlogging, as it is very susceptible to root rot in excessively moist conditions. It does not require frequent pruning, except to remove spent flowers and control its spread.
