What is biggest pine cones?

The biggest pine cones in the world are from the Coulter pine (Pinus coulteri), which is native to California and Mexico. The cones can reach up to 15-20 inches in length and can weigh up to 10 pounds. They are hard and spiky, and each cone contains about 200 seeds. The cones take two to three years to mature and are usually dropped to the ground by the tree after the seeds are dispersed. Coulter pine cones are often used for decorative purposes and can also be used as fire starters. However, collecting them from national parks or protected areas is illegal, so it is important to check with local regulations before taking any.
