This is Yorkshire Gorse growing wild in the Yorkshire Moors. Even the best scientists could never genetically engineer a plant to be more dangerous than gorse, since it is covered with the most razor sharp thorns that would kill anyone unlucky enough to fall into it:
Funny story: until I visited Yorkshire, I’d never heard of gorse before. But in the local dialect it’s pronounced goss, so naturally I assumed it was spelled g-o-s-s. It took me quite some time on Wikipedia to discover the real name of this extremely thorny plant (ulex europaeus).
