A new and distinct cultivar of black walnut tree (Juglans nigra L.) which is distinctly characterized by rapid growth rate, fairly strong central stem tendency, thereby producing good timber qualities. The new variety has good nut bearing qualities. Nut crops are abundant and annual. Nut-bearing begins early in the life of the tree. A new variety of black walnut tree (Juglans nigra L.) was discovered by the applicant near West Lafayette, Ind. in a black walnut planting of seedling progeny from previously selected trees for outstanding timber producing potential. This selection has been designated as BW420, a seedling progeny of BW 205 which is a progeny of BW 97 in records maintained by the applicant on the performance of the selection and grafts made from the selection and will be known henceforth as 'Beineke 8.'
