Railings and ragwort

This morning F and I went bowling in the park.  Afterwards we did a few things in town including visiting the library. When we came out I spotted lots of ragwort plants on the grass of the castle mound.  

I know that ragwort is poisonous for horses but nothing grazes on Oswestry's small castle mound so it's quite safe. Even though the weather was grey and windy, theflowers were still covered in insects.
