This incredible ability means seeds can remain viable for extended periods, sometimes even centuries, by entering a state of suspended animation, only to ## Frequently asked questions ### What is the longest a seed has ever remained dormant before sprouting? The record for the oldest germinating seed belongs to the Arctic lupine (\Lupinus arcticus\), which sprouted after an estimated 10,000 to 12,000 years, recovered from frozen rodent burrows in the Yukon. ### Can I eat dormant seeds? Many common foods are seeds in a dormant state, like beans, lentils, rice, and nuts. However, some dormant seeds are toxic, and others are prepared for consumption in specific ways to make them digestible or safe. ### Do all plant seeds have a dormancy period? No, not all plant seeds exhibit dormancy. Some plants, often those from tropical or consistently favorable environments, produce seeds that germinate immediately upon dispersal if moisture and warmth are present. ### What is the difference between seed dormancy and seed viability? Seed dormancy is a state where a viable seed will not germinate even under ideal conditions due to internal blocks. Seed viability refers to the capacity of a seed to germinate and grow, regardless of whether it's currently dormant or not. ### Why do some seeds need light to germinate while others need darkness? Light can be a crucial environmental cue. Tiny seeds often need light to germinate as it indicates they are near the soil surface and won't be buried too deep. Larger seeds with more energy reserves may germinate in darkness, as they can push through more soil. --- _Source: Planta (https://getplanta.com), the plant care app for iOS and Android.
