I think combining them with a complementary solid would be great. And if you have others fabrics from your stash that will play well with them, that solid would pull them all together. A nine patch might work well, or perphap make a lot of half-square triangles and combine into carpenter's star. Or maybe evening star blocks with the large floral as the center of the star and the others as the star points (either half square triangles or flying geese). You could join with sashing to further pull it all together.
