Different letters reveal statistically significant differences (sequential Bonferroni significance; *p < 0.05, **p < 0.01, ***p < 0.001, nsp > 0.05; ns—non significant) in flower characters using Mann–Whitney pairwise post hoc test. BiH—Bosnia and Herzegovina, HRV—Croatia (min, mean and max; coefficient of variation in %; 14 flowers per population, 1 flower per genet).
