Identification help!

I have a few more unknown items in my garden, the first two are small trees, the last one is a low growing and fast spreading plant. I'm unsure if it is a weed?

 

Looks like Wood Avens (AKA Herb Bennet), does it have yellow flowers (during the flowering season later in the year)? https://en.wikipedia.org/wiki/Geum_urbanum

 

My guess would be olive for no1 and a very chlorotic camelia for No2.
No3 looks like a weed to me, so its probably a very sought after herbaceous plant

 

I am not sure as I only just moved a couple months ago!

 

Lol Thanks, I'm not sure what to do about the poor chlorotic camellia though! It's currently in a pot and probably far too large for it. I could plant it in the ground if it's not going to get too huge, the garden isn't really very large.

 

In the mean time, while you think about it, try a dose of sequestrene and see if it greens up.

 

The third one looks (like @Scrungee suggested) Wood Avens.

To @Sandra-Tingle, if you decide to leave it and it produces yellow flowers in the summer, I'd recommend cutting the heads off before they turn to seed. The seeds are barbed, stick to clothing and animal fur tend and to rip out and sprinkle all over the place if they grow under shrubs etc.
