State
Seed dormancy is a period of suspended growth ending only when species-specific cues — cold, light, fire, or a softened seed coat — signal favorable germination conditions.
Show
A temperate seed requiring vernalization stays dormant through winter cold, germinating only once conditions turn favorable in spring.
Watch for
Dormancy can last months to decades depending on species — not a fixed, universal waiting period.
