Clammy Sowthistle

The Clammy Sowthistle (Sonchus tenerrimus) is a species in the genus Sonchus. Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Common sowthistle

<em>Sonchus oleraceus</em>, commonly known as the common sowthistle, is a cosmopolitan annual herb in the family Asteraceae, native to Europe and western Asia but now naturalised across nearly every continent. This species typically inhabits disturbed ground, roadsides, agricultural fields, gardens, and waste places, thriving in a wide range of soil types and climatic conditions. It is one of the most widely distributed weedy plants on Earth, with a geographic range spanning temperate and subtropical regions worldwide including North America, South America, Africa, Asia, Australia, and beyond. Classified as Least Concern on the IUCN Red List, <em>Sonchus oleraceus</em> is among the most ecologically successful colonisers of human-modified environments. The plant typically grows to 20–120 cm in height, producing distinctive yellow composite flower heads and lobed, spiny-margined leaves with milky latex sap. It completes its lifecycle rapidly, producing numerous wind-dispersed achenes that facilitate broad dispersal. As a plant, dietary traits are not applicable in the animal sense; it is itself consumed as a food source by livestock, insects, and in some cultures as an edible green for humans. Biological traits such as average lifespan metrics remain poorly documented for this weedy annual, though it typically completes its lifecycle within a single growing season.
