| Common Ragwort Senecio jacobaea rapidly occupies any disturbed area. It has dark green leaves deeply divided into lobes that make a basal rosette. The lower leaves die as the flowers mature. The flowerheads are dense and flat-topped. As it is poisonous animals do not usually eat it and it can cover large areas. There is legislation which ought to ensure its control. | Oxford Ragwort Senecio squalidus is common in towns on pavements and rough ground. It has yellow-green leaves and the flowerheads are less densely packed giving a smaller, more open plant than Common Ragwort. The plant derives its name from the town of Oxford where it was introduced into the Botanic Garden and rapidly spread throughout the south and east. | Marsh Ragwort Senecio aquaticus is a slender plant with a single stem and large, well-spaced flowerheads. The leaves extend all the way up the often purple stem. It is common in marshes and wet areas where the other species will not grow.
