Ragwort is one of the better-known wild flowers, due to the fact that it is poisonous to horses. It is actually an offence to allow ragwort to grow on your land, although I am not sure how rigorously the law is enforced, as it can be seen growing on roadsides and in fields all over Ireland. Ragwort is the only food source for the caterpillars of the beautiful crimson-and-black cinnabar moth.
