What is this white five-petal nice-smelling flower on a bush? (vine? It seems to be supported by some tree but I'm not sure it wasn't the tree itself. It also seemed to me when I was taking the picture that the leaves in the picture were the flower's leaves.)
Here is its picture:
I'd also like to know how to grow it. I put a branch in a vase with water, hoping it will sprout roots. But that never happened. But that is a separate question. My question now is what the plant is so I can google how to grow it.
