Birch cones come from birch trees, which are deciduous trees that belong to the genus Betula. The cones of birch trees are typically small, woody, and egg-shaped, and they contain the tree’s seeds.
However, it’s worth noting that not all birch trees produce cones. Some species, such as the paper birch (Betula papyrifera), produce small, cylindrical catkins instead of cones. The catkins are long clusters of tiny flowers that bloom in the spring and release pollen into the air.
If you have found birch cones, it’s likely that they have fallen from a birch tree in your area. You can identify the species of birch tree that they came from by examining the characteristics of the cones, such as their size, shape, and color, as well as the tree’s bark, leaves, and overall appearance.
