I found this pretty bright daisy on an afternoon walk. Known as Oxford Ragwort it presents itself as both a perennial and an annual which is an unusual combination for a plant. It tends to be more common from the Midlands to the South of England although the occasional plant is spotted on the coast in both the lower part of Scotland and the east of both the North and South of Ireland. It occurs in situations similar to the annual poppy, in other words on disturbed ground.
