very vigorously and become erect, uniformly wide, and
densely branched and foliaged. They have reached
heights of over 8.8 meters tall and spreads of over 7
meters in diameter in 30 years. One-year liners of this
hybrid propagated in Oregon by budding are nearly twice
the size of one-year liners of C. kousa as the hybrid
liners typically are 1.2 meters in height and are very
stout.
