Significant interactions between range of origin (native: Europe and North Africa, introduced: Australia and New Zealand) and climatic conditions (mean minimum temperature of the coldest month and mean annual precipitation) for A) Vegetative height at first flower bud (LRTχ2 = 4.04, df = 1, p value = 0.04), B) Carbon-to-nitrogen ratio of seeds (LRTχ2 = 4.84, df = 1, p value = 0.03) and C) Mean number of seeds per flower head (LRTχ2 = 5.21, df = 1, p value = 0.02).
