Sugar pine cones are considered one of the largest cones in the world. They measure 16 to 26 inches long. Another massive cone is found on gray pine trees. The cones measure 8 to 12 inches and some weigh over 2 lbs.
Douglas, white and red firs grow in California. The red fir cones are the largest of the three types of firs. The 6- to 9-inch cylindrical shaped cones fall apart when mature. This is also true of the 3- to 5-inch cones on white fir. Red and white fir cones that stand erect on tree branches are rarely found on the ground. The 3- to 5-inch cones on Douglas firs have three-pronged bracts that cover the cone sides.
Ponderosa pines have oval, 5-inch cones with pointed tips that curve outward. Jeffery pines have pointed tips that curve inward on the 5- to 9-inch cones. Lodgepole pine cones are small, 1 to 2 inches long. Lodgepole cones are tightly closed until heated in a fire. Then the cones open and all of the seeds are released.
Coast redwood trees grow up to 375 feet tall but have 1-inch cones with 14 to 24 tiny seeds. The huge giant sequoias have slightly larger egg-shaped cones, measuring 2 to 4 inches.
Incense cedar trees have 3/4-inch cones with flat, bill-shaped sides. The mature cones look like tiny flying geese. Western juniper tree cones look like berries. The small blue-black female cones contain one to four brown seeds.
