Cultivation

Origin: about 1903 as a seedling tree on the Stone Ranch near Fullerton, Calif., from nuts obtained from the Meek estate in Hayward, Calif. The parent tree was thought to be a Persian or Kaghazi type from Iran. Nut: elongated and rounded at both ends, shell quality excellent, seal good, but kernel color is poor. Tree: leafs out one week and harvests one to two weeks after Payne, little fruitfulness on lateral buds. Yield is moderate. Not highly susceptible to sunburn, but it is late maturing and susceptible to frost. If selfed, Eureka give one-quarter albinos. Fruit:
