Walnut ‘Meyric’ produces large walnuts and prefers free-draining soil. It typically starts producing walnuts at around five years of age. The brown nuts are held in a green husk. While Walnut ‘Meyric’ is self-fertile, it can produce better crops when planted with another walnut cultivar like Walnut ‘Shannon’ or Walnut ‘Wilson’s Wonder’. Walnut is deciduous and native to the region stretching from the Balkans eastward to the Himalayas and southwest China. Learn more about Walnut. Walnut ‘Meyric’ was discovered by Chris Ryan in Hawkes Bay, New Zealand and then propagated by Vernon Harrison.
