Stinking Willy

Poisonous to horses, beloved by the Cinnabar Moth, Ragwort is all over the lanes and there are no mobs of horse lovers pulling it up.

We once holidayed in a secluded valley in Devon and were awoken one morning by gangs of raucous young women in riding gear, with spades, who proceeded to denude the valley of every single yellow flower. Some of the weren't even ragwort.

What larks, Eh?
