This new variety, ‘Ivanhoe’, comes into bearing young, with an excellent yield. ‘Ivanhoe’ forms large-sized walnuts that possess light-colored kernels with little size variation in a given harvest. ‘Ivanhoe’ bears fruit terminally and laterally and yields a crop that can be harvested approximately 4 weeks before ‘Chandler’ (U.S. Plant Pat. No. 4,388). ‘Ivanhoe’ is also protogynous, bearing female flowers before male flowers.
