I like your floral and I loved the original arrowheads with white and these print ones, too, but IMHO neither the colors nor the arrowhead pattern works with the floral. There are lots of good ideas offered above but I think I'd stop trying to match the colors in the floral and use a cream or tan or a pastel version of one of the print colors. An all-over lattice , for example, could showcase the floral.
