The knobcone pine, Pinus attenuata (also called Pinus tuberculata), [2] is a tree that grows in mild climates on poor soils. It ranges from the mountains of southern Oregon to Baja California with the greatest concentration in northern California and the Oregon-California border.

Nov 12, 2020 · Knobcone pines are different. Known as closed cone pines, knobcones require heat, usually from fire, in order to open up and release their seeds. This classic plant adaptation to fire is because the cones are effectively glued shut with resin, a phenomenon called serotiny. When the heat of fire melts the resin, the ¼-inch black seeds are released.

Knobcone pine has been called the "tree that swallows its cones". The heat of a fire causes the cones to open and shed their seeds. Numerous seedlings then begin a new forest.
