Giant pine cones are rare; most cones fall in the small to medium categories. Giant pine cones are between 10 and 12 inches long, with some growing even bigger than that. The Coulter Pine and the Sugar Pine grow giant pine cones. Extreme cold and heat help the pine cones to grow to the giant proportions, so they only get that large in certain areas of the country. Getting a pine cone to open requires heat, and you can do it at home in the oven.

Tips and warnings

  • Putting the pine cones in the oven will also kill any bugs that may be living inside them.
  • Use pot holders to pull the baking tray out of the oven, as it will be hot.
  • Do not turn the oven temperature higher than 93.3 degrees C, or you run the risk of burning the pine cones.
