Walnut Flower, Fruit & Cultivar Photo Gallery
Walnut is a deciduous tree with separate male and female (imperfect) flowers. Pollen dispersal and pistillate flower receptivity occur at different times for each variety. Planting at least two varieties that have overlapping pollen dispersal and flower receptivity is necessary to ensure adequate pollination and fruit set.

The UC Davis Walnut Breeding Program is a long term program to provide the California walnut industry with improved walnut cultivars and rootstocks and to develop knowledge that will increase the efficiency of walnut breeding. We thank Gale McGranahan and Chuck Leslie, UC Davis Walnut Breeding Program Leaders for providing the the walnuts in the photos.
