The nut has a smooth, brown, thick shell, that contains a small edible nutmeat. Hind's Walnut (Juglans hindsii) is a severe allergen. Pollination: Occurs in following seasons depending on latitude and elevation: Spring. "Juglans hindsii" has been commercially important as a rootstock for orchard stock of "Juglans regia" (English walnut) trees all over the world. It is also used as a parent to the fast-growing Luther Burbank hybrid, commonly called "Paradox" ("Juglans
Fruit tree pollination Fruit tree pollination Pollination of fruit trees is required to produce seeds with surrounding fruit. It is the process of moving pollen from the anther to the stigma, either in the same flower or in another flower. Some tree species, including many fruit trees, do not produce fruit from self-pollination, so pollinizer trees are planted in orchards. The pollination process requires a carrier for the pollen, which can be animal, wind, or human intervention (by hand-pollination or by using a pollen sprayer). Cross pollination produces seeds with a different genetic makeup from the parent plants; such seeds may be created
