More mystery growth ...

Some more mystery growth which I hope people can help us identify. I suspect that both of these may be crops which have just overgrown and gone to seed since the last allotment tenant gave up and scarpered. I feel like I should find out, because if they are some kind of pesky weed and there are problems like deep taproots that I should be aware of, I can do something sensible about it rather than just hacking and slashing indiscriminately and exacerbating the problem.


Sorry for the blurriness of this picture, but it was on the end of a tall thin stalk and I wasn't tall enough to get any closer. The blurriness is caused by a tight zoom and hand shake. I have a feeling this might be a carrot plant that's gone to seed. Am I right?


Another crop gone to seed? If so, what?

What is this?

Help! We don't know what this is. Can anybody indentify it? I've not found it in any of the books yet. I'll be honest, we're probably going to dig it up anyway, but it would be nice to know.
