Uses

Edible uses

Notes

Seed - raw or cooked[1]. Very tasty[2]. The seed makes an excellent dessert nut, tasting just like the cob and filbert[183, K]. It can also be dried and ground into a powder then used in making nut milks, bread etc[1]. 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[3]. 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[3]. Germinates in 1 - 6 months at 20°c[3]. 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]. This species is a hybrid and will not breed true from seed. Layering in autumn. Easy, it takes about 6 months[4][5].

Cultivation

An easily grown plant, it succeeds in most soils, but is in general more productive of seeds when grown on soils of moderate fertility[6][5]. It does less well in rich heavy soils or poor ones[6][7]. Does well in a loamy soil[6]. Very suitable for an alkaline soil[6], but it dislikes very acid soils[8]. Plants are fairly wind tolerant[9][6].

A hybrid of garden origin, it combines the non-suckering, winter hardiness and vigorous growth of C. colurna with the free-falling, early bearing and large nut size of C. avellana[1]. There are some named varieties, selected for their edible seeds[1][5].

Members of this genus bear transplanting well and can be easily moved even when relatively large[6].
