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.
