Spruce cones are the reproductive structures of spruce trees, which belong to the Picea genus. These cones are typically elongated and can vary in size, usually measuring between 1 to 6 inches long. They are composed of overlapping scales that protect the seeds inside. Spruce cones can be found hanging from the branches of the tree and are often green when immature, turning brown as they mature. Once the seeds are ready to be dispersed, the cones open up to release them, often aided by wind. The seeds are small and winged, allowing them to travel away from the parent tree. Spruce cones play a crucial role in the life cycle of coniferous trees and contribute to forest regeneration.
