plants have developed varius types of seed Dormancy is a mechanism to prevent germination during unsuitable ecological conditions, when the probability of seedling survival is low.
One important function of most seeds is delayed germination, which allows time for dispersal and prevents germination of all the seeds at same time. The staggering of germination safeguards some seeds and seedlings from suffering damage or death from short periods of bad weather or from transient herbivores; it also allows some seeds to germinate when competition from other plants for light and water might be less intense. Another form of delayed seed germination is seed quiescence, which is different than true seed dormancy and occurs when a seed fails to germinate because the external environmental conditions are too dry or warm or cold for germination. Many species of plants have seeds that delay germination for many months or years, and some seeds can remain in the soil seed bank for more than 50 years before germination.

Why do some plants die when it gets cold?
Some plants are adapted to cold temperatures and survival through snow and frost; others plants that originate in more temperate areas are not able to withstand snow or frost and will die. Plants which normally grow in cold climates have mechanisms as well as chemical "anti-freeze" to prevent them being damaged or killed in cold weather
