Help me identify these flowers/plants

kkudi

I am attaching two different photos that I would like to know what kind of plants they are called if possible. 

Flinster

They are peony’s, I don’t know the variety though.

Borderline

In both pictures, they are Peonies. In the second photo, there is a Caper Spurge, Euphorbia Lathyris growing behind it.

is the caper spurge considered some kind of weed? or is it a plant in its own right?

Borderline

I consider it a weed, and will advise you wear gloves if you are digging it out. There is a milky sap if you break the stalks. Can cause irritation on the skin.
