https://flic.kr/p/75DYFJ | Wild carrot | This is growing just outside my front door, so I took a photo of it. They're normally small and green, but this one was much larger and white with little pink prickly things that look like small Venus flytraps. This one had a head of about 10cm and is almost 1m tall. When they're green, they're about half that. I took it a few days ago in SW France.
