I'd do something different than everybody else. I would probably do a three color sashing in one of the pink tones, then a green as close to the leaf color as I could find and one of the yellows in other flowers and then I'd do 9 patch cornerstones so it looks like the colors weave in the cornerstones. You can be very creative with sashing and get several different looks.
You really have to pay attention to which way the colors go when you do a 3 color sashing though!!
