Seed - raw or cooked
. The seed, which has a hard shell, is of relatively good flavour
. 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.
There are no material uses listed for Corylus heterophylla.
The seed is digestive and appetizer
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[K].
Layering in autumn. Easy, it takes about 6 months.
Division of suckers in early spring. Very easy, they can be planted out straight into their permanent positions.
