The male catkins can be eaten. Inner bark - dried, ground into a powder and then used as a thickener in soups etc or added to cereals when making bread. An emergency food, it is only used when all else fails. Immature female cones - baked.A vanillin flavouring is obtained as a by-product of other resins that are released from the pulpwood.
The needles contain a substance called terpene, this is released when rain washes over the needles and it has a negative effect on the germination of some plants, including wheat. Oleo-resins are present in the tissues of all species of pines, but these are often not present in sufficient quantity to make their extraction economically worthwhile. The resins are obtained by tapping the trunk, or by destructive distillation of the wood. In general, trees from warmer areas of distribution give the higher yields. Turpentine consists of an average of 20% of the oleo-resin and is separated by distillation. Turpentine has a wide range of uses including as a solvent for waxes etc, for making varnish, medicinal etc. Rosin is the substance left after turpentine is removed. This is used by violinists on their bows and also in making sealing wax, varnish etc. Pitch can also be obtained from the resin and is used for waterproofing, as a wood preservative etc.Wood - a useful timber tree in Japan, but it is unlikely to be of much value in Britain. The timber is used for construction, poles, and furniture.
Practical Plants is currently lacking information on propagation instructions of Pinus densiflora. Help us fill in the blanks! Edit this page to add your knowledge.
Leaf secretions inhibit the germination of seeds, thereby reducing the amount of plants that can grow below the tree. The plant is quite fast growing when very young but this soon tails off and the tree is then quite slow growing. Cultivated for its wood in Japan, but it is unlikely to be a worthwhile timber tree in Britain. Plants are strongly outbreeding, self-fertilized seed usually grows poorly. They hybridize freely with other members of this genus. Hybridizes in the wild with P. thunbergii. There are many named forms of this species.Plants in this genus are notably susceptible to honey fungus.
