The butternut or white walnut is one of the hardiest nut trees, A North American native, the nut has a rich, buttery flavor used in baking, confections, and eating fresh. The attractive, light golden wood is used for paneling and furniture. Trees grown from seed will begin to produce nuts in about 10 years.
The butternut tree has distinctive, ridged and furrowed bark and a short, usually forked trunk with a wide, spreading, open crown. The late spring blooms can be damaged by late frosts. It is an alternate bearer meaning it will bear abundantly one year, less the next year or take a few years off before bearing again. The nuts store well. (Plant multiple trees to ensure pollination.)

Rate of growth refers to the vertical increase in growth unless specified differently. Rate, as is true for size, is influenced by numerous variables such as soil, drainage, water, fertility, light, exposure, ad infinitum. The designation slow means the plant grows 12” or less per year; medium refers to 13 to 24” of growth per year; and fast to 25” or greater.Manual of Woody Landscape Plants, by Michael Dirr.
