Help ID these plants, please
Now that things are starting to bloom I'm wondering if some more of the plants in my new garden are weeds or not. Can you help ID the below? Thanks!
1. This one is pretty, but it's encroaching on some other plants.
2. This one is taking over my beds, so I am thinking it's a weed?
3. Am looking mainly for an ID on the large-leaved plant in the middle please.
4. This popped up near the conservatory wall a couple weeks ago.
