Higher seed mass and warm germination temperature contributed to higher and faster germination. However, the effects of temperature and moisture interacted leading to low germination and high proportion of dormant seeds in warm, dry conditions. Seeds of plants originating from warm climate had higher germination than those from cold climate, the effects of original climate were partly due to differences in seed mass. Total germination negatively correlated with plant performance variables contributing to vegetative reproduction. Both conditions of plant origin and of germination determine species' germination and the effect of plant origin can partly be explained by seed mass. We confirmed a trade-off between generative and vegetative reproduction indicating that, depending on the actual conditions, the species is able to modify investments to generative or vegetative reproduction.
