Physical Characteristics

An evergreen tree growing to 20m by 5m at a fast rate. It is hardy to zone 5. It is in leaf all year, in flower in May, and the seeds ripen from October to November. The scented flowers are hermaphrodite (have both male and female organs). We rate it 2/5 for edibility and 0/5 for medicinal use.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It requires moist soil.

Habitats and Possible Locations

Woodland, Canopy.

Edible Uses

Flowers; Inner bark; Seed; Tea.

Young male catkins - raw or cooked. Used as a flavouring[172].
Immature female cones - cooked. The central portion, when roasted, is sweet and syrupy[172].
Inner bark - dried, ground into a powder and then used as a thickener in soups etc or added to cereals when making bread[172]. An emergency food, it is only used when all else fails.
Seed - raw. Too small and fiddly to be worthwhile unless you are desperate[172].
A refreshing tea, rich in vitamin C, can be made from the young shoot tips[172].

Medicinal Uses

Disclaimer

None known

Other Uses

Resin; Tannin; Wood.

Tannin is obtained from the bark[74].
Turpentine is obtained from the bark and branches[74].
Wood - soft, white, easily cleaves, light, durable, has a good resonance. Used for construction, furniture etc[74]. It is also valued for its use in the pulp industry to make paper[171].

Cultivation details

Likes abundant moisture at the roots, if grown in drier areas it must be given a deep moist soil[11]. Tolerates poor peaty soils[200]. Succeeds in wet cold and shallow soils but is not very wind-firm in shallow soils[1]. Prefers a pH between 4 to 6[200]. Dislikes shade[200]. Intolerant of atmospheric pollution[11]. Resists wind exposure to some degree[200].
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[200].
Plants are strongly outbreeding, self-fertilized seed usually grows poorly[200]. They hybridize freely with other members of this genus[200]. There are a number of named forms selected for their ornamental value, most of these are dwarf cultivars[200].
Young trees are slow growing at first but from the age of about 5 - 6 years they can grow up to 1 metre a year and this can be maintained for the next 70 years or so. Growth virtually ceases by the time the tree is 90 - 100 years old[185]. Increases in girth follow the same pattern as height increases[185]. Trees probably do not live much longer than 100 years in Britain[185]. They are occasionally planted on a small scale in Europe as a timber tree[50].
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[200].
The bruised leaves have a resinous aroma[245].

Propagation

Seed - stratification will probably improve germination so sow fresh seed in the autumn in a cold frame if possible[80]. Sow stored seed as early in the year as possible in a cold frame[78]. A position in light shade is probably best[78]. Seed should not be allowed to dry out and should be stored in a cool place[80]. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse or cold frame for their first winter. They can be planted out into their permanent positions in early summer of the following year, or be placed in an outdoor nursery bed for a year or so to increase in size. They might need protection from spring frosts.
Cuttings of semi-ripe terminal shoots, 5 - 8cm long, August in a frame. Protect from frost. Forms roots in the spring[78].
Cuttings of mature terminal shoots, 5 - 10cm long, September/October in a cold frame. Takes 12 months[78].
Cuttings of soft to semi-ripe wood, early summer in a frame. Slow but sure.

Scent

Leaves: Crushed
The bruised leaves have a resinous aroma[245].

Cultivars

''
There are some named forms for this species, but these have been developed for their ornamental value and not for their other uses. Unless you particularly require the special characteristics of any of these cultivars, we would generally recommend that you grow the natural species for its useful properties. We have, therefore, not listed the cultivars in this database[K].
