Your top is beautiful. May I suggest that you finish with the green fabric strip, same size as you were using for the next border. This will finish framing the quilt.
Then take the white fabric, if you still have some, and make about a 3-4 inch border. Applique a simple vine with leaves and flowers like the ones in the quilt itself on this border.
The binding could be a multi-colored green that reads like a solid or maybe even a multi-colored flower fabric with a very, very small print. The colors of the flowers should blend with the colors in the quilt.
Good luck. Glad to hear you are feeling better. I was out for 10 weeks (for 4 weeks, I felt like part of the furniture) most of the time I had what my brother called "sleeping sickness" so I couldn't have quilted if I wanted to.
Great life lessons, too. ROTFL
