Definately the white

I like the green. I would suggest, however, to put both "samples" on a design wall (or someplace where you can look at them for awhile) and see how they "feel" to you after viewing for a couple of days.I've done this twice with quilts for which I could not decide which border to use and was surprised at what a difference time made in my "feelings" for the color schemes.

The green makes it pop. I vote green. Very nice quilt.

I'm partial to the white border, but the works well also, maybe alternate. But, I agree with the others, it does need the border

i really like the green as a border. It seems to bring the rest of the quilt out more.

I like the green.

I'm probably not going to help much but, I like the contrast with the green.

I like the green and a border of black maybe?? Nice quilt.

Definitely a border, both are nice, I lean a little toward the white because you have a lot of green in the prints. I'm sure any way you go the quilt will be beautiful. Good job.
