Ponderosa pine regenerates by seed, with cones maturing in a two-year cycle. The tree flowers from April to June of the first year, and cones mature and shed seeds in August and September of the second year. Seeds are relatively small (7,000 to 23,000 in one pound) and fall only about 100 feet from the parent tree.
