Identification: Chinese Plant Identification Please :)

I was given this plant as a gift from a chinese lady and she called it a Peace Plant. I have searched the net with no results.I know that if you cut the top off of a leaf and stick it in dirt it will grow, also when it flowers it only flowers for a few hours then the flower dies, I have never seen a flower yet. I am curious as to what it is and how to care for it. See pictures.

Thanks for your help :)

 

Looks like Epiphyllum sp., Orchid Cactus.

 

Epiphyllum in need of some pruning by the looks of it.

 

Gooseneck cactus (Epiphyllum oxypetalum). Frequently asked about on garden forums, including this one. Tall habit is normal, train up a trellis or tripod. Can grow quite large.

 

Thank you all for your replies. Now I have somewhere to start looking for care of this plant.

 

It is Epiphyllum oxypetalum of Cactaceae Family. Commonly called as Bethlehem lily.
