Grow in fertile, medium moisture, well-drained soils in full sun. Tolerates some light afternoon shade and some drought. Salt tolerant.
Pinus thunbergii commonly known as Japanese black pine, is noted for its whitish terminal buds that provide interesting contrast with its dark green foliage. In optimum growing conditions, this tree will grow in a generally conical form to 100’ tall, spreading somewhat irregularly with age. In cultivation, it is more often seen in the 20-60’ tall range. Needles (to 4.5” long) in bundles of two are an attractive dark green. Young foliage candles are upright.
Specific epithet honors Carl Peter Thunberg, 18-19th century Sweedish physician.
Healthy, well-maintained trees usually have few major problems. Nematodes are a problem in some areas. These trees may struggle in the St. Louis area where environmental conditions do not favor most conifers.
Good specimen pine. Also may be grown as bonsai.
