A species of tall pines of the Pinaceae family found on ridges and mountainside, it is the most common type of bonsai of pines. It reaches a height of 30m and spreads thick branches horizontally. The bark of the trunk is reddish brown and flaky in scales. The needles are 2-6cm long and somewhat soft. In June, numerous purple-red male flowers appear at the base of the new branches (green), and 2-3 pale green or purple-red female cones appear at the tips. The following autumn, the egg-shaped, oblong cones measuring 4-10cm in length ripen and open, scattering two winged seeds from each scale.
