Juglans hindsii has been widely used as a rootstock for grafting Juglans regia and has been planted extensively in many parts of California for this purpose. It is now naturalized in many areas where it apparently did not occur before the introduction of commercial walnut growing. Possibly some of these naturalized populations are introgressed with Juglans nigra since spontaneous hybridization between Juglans hindsii and Juglans nigra has been reported in areas where both species have been planted. Currently most commercial walnut orchards use hybrid rootstocks, usually Juglans hindsii × Juglans regia[
