Effects of R. ferrugineum patch floral display on (A) mean seed set per patch for control flower s (IN treatment, N =28 patc hes; y  = −0.037 x + 0. 857; green circles; solid line) and emasculated flowers ( EN treatment, N =27 patches; y =0.017 x +0.406; blue triangles; dashed line) and (B) mean reproductive assurance per patch ( N =27 patches; RA =1 - emasculated/control; y  = −0.035 x 2 + 0.304x - 0.348). See Table 1 for methods and statistical comparisons of treatments and Additional file 1: Table S1 for seed sets and pollination parameters per patch.
