Pine trees grow chiefly in the wild cold and taiga forests of the northern hemisphere, particularly in Siberia and Canada. They are huge, straight erect trees with a large stem which may reach up to 75 feet in height with pyramidal or umbrella-like dense foliage cover.The "flowers" of pine tree subsequently develop into a cone. The female cones take about two–three years to mature after pollination. At maturity, the female cones (ovulate or seed cones) may reach from as small as 3 cm long to a very large one reaching about 35 cm. Scales at the base and tip of the cone tend to be small and sterile, and therefore, bear no seeds. Once mature and dry, the cone naturally split open to release the kernel.
