Butternut is a small to medium-sized tree averaging 40 to 60 feet (12-18
m) in height and 12 to 24 inches (30-60 cm) in d.b.h. This tree has a
short trunk which is divided into a few ascending limbs with large
spreading, sparsely forked branches. The smaller branches tend to bend
downwards and then turn up at the ends. The crown is open, broad,
irregular in outline and rounded at the top. The root system is
composed of a number of wide-spreading laterals that grow to a
considerable depth. Usually a taproot develops in deep soils [7,21,24].
Butternut grows fast, especially as a seedling, but usually does not
live longer than 75 years [5,21,24].
