Help identifying a plant?

Question

I found a plant in my backyard, and while I'm sure its nothing exotic or rare, it was nice looking and the only of its kind and I took it upon myself to see if I could pot it and get it to continually grow. I would just like to know the name of it, so I can stop calling it 'flower', hehehe.

Heres a few pictures I took of it:

Also, when I cut it, a thin white liquid came of it with no immediate scent. I made sure not to touch it just in case =). Thanks for any help in advance.

You have a Euphorbia marginata also called Snow on the Mountain.

You show excellent sense! It is a good idea not to touch latex from any euphorbia as some people are sensitive to it. It is very bad if rubbed into an eye so always wash after handling one.
