Uses
Edible uses

Seed - raw or cooked[8][2]. Rich in oil. The seed ripens in mid to late autumn and will probably need to be protected from squirrels[K]. When kept in a cool place, and not shelled, the seed should store for at least 12 months[K]. An edible oil is obtained from the seed.

Propagation

Seed - best sown as soon as it is harvested in autumn in a cold frame[4]. 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[4]. Germinates in 1 - 6 months at 20°c[4]. 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[K]. Layering in autumn. Easy, it takes about 6 months[10][7].
Cultivation
This section contains historical Plants For A Future notes marked noncommercial.
An easily grown plant, it succeeds in most soils, but is in general more productive of seeds when grown on soils of moderate fertility[3][7]. It does less well in rich heavy soils or poor ones[3][9]. Does well in a loamy soil[3]. Very suitable for an alkaline soil[3], but it dislikes very acid soils[5]. Plants are fairly wind tolerant[1][3]. This species is cultivated for its edible seed in Asia[8], it frequently sets fruit at Kew[3]. Closely allied to C. colurna[3], and considered to be no more than a sub-species by some botanists, it is an upright growing tree that does not produce suckers[6]. Members of this genus bear transplanting well and can be easily moved even when relatively large[3].
