Pinus thunbergii

Bloom Color: Yellow. Main Bloom Time: Early spring, Late spring, Mid spring. Form: Pyramidal.

Pinus thunbergii is an evergreen Tree growing to 15 m by 7 m at a medium rate.
It is hardy to zone 6. It is in leaf all year, in flower from April to May, and the seeds ripen from January to February. The species is monoecious and is pollinated by Wind. The plant is not self-fertile.
Suitable for: light and medium soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: acid and neutral soils. It cannot grow in the shade. It prefers dry or moist soil and can tolerate drought. The plant can tolerate maritime exposure.

Landscape Uses:Firewood, Screen, Seashore, Specimen. Thrives in a light well-drained sandy or gravelly loam. Dislikes poorly drained moorland soils. Established plants tolerate drought and maritime exposure. The Japanese black pine bears cones whilst still young and produces cones very freely in Britain. The trees thrive in Britain but do not grow very large and are probably not going to be long-lived. Young trees grow about 50cm per year but this soon tails off and older trees average less than 30cm per year. Plants are strongly outbreeding, self-fertilized seed usually grows poorly. They hybridize freely with other members of this genus. This species hybridizes in the wild with P. densiflora. Leaf secretions inhibit the germination of seeds, thereby reducing the amount of plants that can grow under the trees. Plants in this genus are notably susceptible to honey fungus. Special Features:
Not North American native, Inconspicuous flowers or blooms.
