Really does resemble a weed

Be interesting to wait and see what it flowers like.

The size it is I think I'd be yanking it our smartish.

Gracious! It's taken over, hasn't it...whatever it is. Sorry I don't recognise it at all.

Have got something similar in my greenhouse, with flowers. Looks the same, Thorn Apple.Don't want to worry you but it is Highly poisonous. Picture on my question page.

No, the leaves are far too small for Datura (Thorn Apple). So are the spines soft or hard on the leaves. We have two different things which look like this, the difference is that one is soft and has yellow flowers, the other, the spines are very stiff and break off in the skin so painfully. That has purple thistle like flowers.
