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.
Small quantities of resin are obtained from between the bark and the wood.Wood - soft to moderately hard. Used in construction, shingles, crates, household purposes etc. It is also valued for its use in the pulp industry to make paper. An indifferent fuel but it yields a fairly good charcoal.

Most trees are only hardy to zone 8 (tolerating temperatures down to about -5 to -10°c) but selected clones can succeed in zone 7 with temperatures down to -15°c. 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. Difficult to establish because it is sensitive to frost until it is 1.5 metres or more tall, young plants should be given a position sheltered from the early morning sun. Established trees can grow quite vigorously making new growth of 60cm per year for a number of years. Plants in general are slow-growing.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.
