Urban Thistle

Onopordum urbanum

Generation 5 · descended from Onopordum acanthium (Scotch Thistle) · evolved in urban

The Urban Thistle evolved from Onopordum acanthium as a response to the harsh conditions of city life. Intense sunlight, lack of water, and constant disturbance by humans led to the development of a deep taproot and tough, waxy coatings. Its thorns became more effective at deterring both animals and humans, allowing it to thrive in the cracks of sidewalks and building facades.
