What flower is this?

I was told it was a daylily. Then a neighbor told me it was a Peony. Is that correct? Is a Peony the same as a Peonies? Anyway, I was given a few plants to give to my mom and I want to find out how to care for them. I tried to research it and haven't found a thing with any of the names I was told. Here are pictures of its flower and another of its leaf:

What flower is this?
I am 99% sure it's a Peony and yes they are the same





Peony = single flower


Peonies = multiple flowers
Reply:Yes, peony. I am not sure of the variety. Ours were all purple flowers.


But that is a peony and the leaf is peony leaf.


Here is a web page
