A large, fast growing tree to 30m (100 ft) high with deeply furrowed bark and large leaves. Needs a sunny location. Nuts are produced here in good summers (needs 2 or more trees), and are sweet, oily and rich. Hardy to -25°C. Plants are grafted or seedling trees from known mothers, 15-30 cm high. Note that seedling trees will not be identical to the mother tree so there may be variation in the nut shape and size.
