A new and distinct cultivar of black walnut tree (Juglans nigra L.) which is distinctly characterized by extremely rapid growth rate, fairly strong central stem tendency, thereby producing good timber qualities. The new variety has low production of nuts. This new variety of black walnut trees was discovered by the applicant near South Raub, Tippecanoe County, Indiana in a black walnut planting from previously selected trees for outstanding timber production potential. This selection has been designated as BW508, a seedling progeny of patented Purdue-I (U.S. Plant Pat. No. 4,543) in records maintained by the applicant on the performance of this selection, and grafts made from the selection and will be known henceforth as Beineke 11.
