Cultivation Details

An easily grown plant, it succeeds in most soils, but is in general more productive of seeds when grown on soils of moderate fertility[, ]. It does less well in rich heavy soils or poor ones[, ]. Does well in a loamy soil[]. Very suitable for an alkaline soil[], but it dislikes very acid soils[]. Plants are fairly wind tolerant[, ].
This species is cultivated for its edible seed in Asia[], it frequently sets fruit at Kew in London (hardiness zone 7)[].
Closely allied to Corylus colurna[], and considered to be no more than a sub-species by some botanists, it is an upright growing tree that does not produce suckers[].
Members of this genus bear transplanting well and can be easily moved even when relatively large[].

Edible Uses

Seed - raw or cooked[, ]. Rich in oil.
The seed ripens in mid to late autumn and will probably need to be protected from squirrels[]. When kept in a cool place, and not shelled, the seed should store for at least 12 months[].

An edible oil is obtained from the seed.

Medicinal

The seeds are considered to be tonic[].

Other Uses

The pinkish-white wood is firm, moderately hard and durable. It can be used for making furniture, turnery etc[, ]. It is only used locally, but it is well grained and does not warp, and deserves to be better known, especially as many specimens shew a fine shining grain resembling Bird's-eye Maple[].

Propagation

Seed - best sown as soon as it is harvested in autumn in a cold frame[]. Germinates in late winter or spring. Stored seed should be pre-soaked in warm water for 48 hours and then given 2 weeks warm followed by 3 - 4 months cold stratification[]. Germinates in 1 - 6 months at 20°c[]. When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame or sheltered place outdoors for their first winter. Plant them out into their permanent positions in late spring or early summer[].
Layering in autumn. Easy, it takes about 6 months[, ].
