It looks great either way; just depends on whether the added size is important to you or not. If not, I'd stick with just the green.
Here's something regarding borders that really rings true for me... "A multicolor quilt will appear to be whatever color the border is." If you want a "green" quilt, leave it with just the green, if you want a "gold" quilt, add the gold border.
