Which vase is better?

I found this poor little arrangement last week and it needs a vase to live in.
I fell in love with the colors.  You tell me....which vase below does it belong in?
A
B
Of course, I'll add moss to the bottom of the base to cover the foam.
I'll add some other plant/floral elements to it to make it fuller as well.
Tell me what your vote is?
I'm participating in Metamorphosis Monday.  Go here to see other before and after projects.
Have an awesome week!
