Physical Characteristics

An evergreen tree growing to 40m. It is hardy to zone 9. It is in leaf all year, in flower in June, and the seeds ripen from September to October. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by Wind. We rate it 2/5 for edibility and 0/5 for medicinal use.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained soil. 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

Seed.

Seed - raw, cooked or ground into a powder[1, 2, 81, 157, 183]. Starchy and delicious, it has the texture of a waxy boiled potato with the flavour of chestnuts[183]. Large, it is an important food source for the Australian Aborigines[156]. Cones can be up to 4.5 kilos in weight and contain up to 150 seeds[1]. The germinating seed produces an underground 'earth nut' which has a coconut-like flavour[183].

Medicinal Uses

Disclaimer

None known

Other Uses

Wood.

Wood - soft, easily worked, high quality. Used for cabinet making, flooring, plywood etc[156]. The branches are used for fencing and fuel[272].

Cultivation details

Succeeds in most soils[157]. Plants are resistant to salt spray[157].
Not very hardy outdoors in Britain, it requires a cool greenhouse in most parts of the country[1]. Some provenances should be hardy at least in the milder areas, there is one tree growing in &ndndndnd at Glendurgan gardens[81]. It was 10 metres tall in 1965[185].
This species is hardy to about -5° c, with occasional lows to -8° c, but it is liable to be killed in severe winters even in the Scilly Isles[200].
In Australia, each Aboriginal family would own a group of trees and these would be passed down from generation to generation[2]. This is said to be the only case of hereditary personal property owned by the Aborigines[2].

Propagation

Seed - best sown as soon as it is ripe in a greenhouse[134] or it can be stored cool and moist then sown February in a greenhouse[78, 80]. The seed usually germinates in 1 - 2 months at 15° c[134]. As soon as they are large enough to handle, prick the seedlings out into individual pots. The plants have a rather sparse root system and are best placed in their final positions as soon as possible. Give them some protection from the cold for at least their first winter[K].
