vernalisation
Many plants have a vernalization requirement, that is, they actively repress flowering until after a period of prolonged cold, in order to align seed production with the favourable environmental conditions of spring. Vernalization occurs during the cold, but flowering only occurs many weeks or even months later when other specific conditions, including the presence of certain photoperiods and ambient temperatures, are also met.
