Thunderhead Japanese Black Pine will grow to be about 10 feet tall at maturity, with a spread of 15 feet. It tends to fill out right to the ground and therefore doesn't necessarily require facer plants in front, and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live for 80 years or more.

This pine should only be grown in full sunlight. It prefers dry to average moisture levels (once established) with very well-drained soil, and will die in standing water. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments.
