Care tips
This species is not typically cultivated as an ornamental plant, as it is a common weed. It thrives in full sunlight and moist soils, often appearing in cultivated fields and disturbed areas. It does not require specific watering or fertilization, and the main 'care' usually involves controlling its spread due to its spiny seeds. A common mistake is underestimating its dispersal capability.
