Etnobotánica:

Valuable for lumber which is often used for cabinetry. People eat the nuts, but they are difficult to extract from their shells.

Comentarios generales:

Will not produce flowers/seed unless it gets adequate winter cold, hence not recommended for use south of its native range. Salt spray tolerance was based on comments about tolerance to winter road salt in the northeastern US.
