A new and distinct cultivar of black walnut tree ( Juglans nigra L. ) which is distinctly characterized by extremely rapid growth rate, very strong central stem tendency, and excellent straightness, thereby producing excellent timber qualities.

This selection has been designated as BW429, a seedling progeny of BW 41 in records maintained by the applicant on the performance of the selection and grafts made from the selection and will be known henceforth as ‘Bieneke 9.’
