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, earlier than average time of leafing, and good straightness (little sweep and few crooks) thereby producing excellent timber qualities. The new variety has poor nut bearing qualities. Nut crops have been irregular and very light to none. This new variety of black walnut tree was discovered by the applicant in West Lafayette, Ind. in a yard area, and was discovered in the course of a search for unique and high quality black walnut trees to be utilized in breeding for outstanding timber producing potential. This selection has been designated as BW130 in records maintained on the performance of grafts made from the original selection and will be known henceforth as Tippecanoe-1.
