Immature female cones - cooked. The central portion, when roasted, is sweet and syrupy. 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. Seed - raw. Too small and fiddly to be worthwhile unless you are desperate.A refreshing tea, rich in vitamin C, can be made from the young shoot tips.
Cuttings of semi-ripe terminal shoots, 5 - 8cm long, August in a frame. Protect from frost. Forms roots in the spring. Cuttings of mature terminal shoots, 5 - 10cm long, September/October in a cold frame. Takes 12 months.Cuttings of soft to semi-ripe wood, early summer in a frame. Slow but sure.

This species is not very successful in Britain. Whilst it is very cold-hardy when dormant, it comes into new growth too early in the spring and this growth is often cut back by late frosts. The few trees that can be found are stunted and poor due to repeated frost damage. The sub-species P. jezoensis hondoensis. (Mayr.)Rehder. is much more successful, it shows remarkably consistent growth in all parts of the country. Though not of the fastest, older trees average 40cm increase a year. Increase in girth is more rapid, 4cm a year is common. In some upland areas, especially over granitic or other base-poor soils, growth rate and health have been seriously affected by aluminium poisoning induced by acid rain. Plants are strongly outbreeding, self-fertilized seed usually grows poorly. They hybridize freely with other members of this genus.Trees should be planted into their permanent positions when they are quite small, between 30 and 90cm. Larger trees will check badly and hardly put on any growth for several years. This also badly affects root development and wind resistance.
