History and significance:
The tree is named after Thurston County pioneer George Bush, who led wagon trains of families from Missouri to settle on the western side of what would become the states of Washington and Oregon. Along with Tumwater founder Michael T. Simmons, Bush staked a claim to farm 640 acres south of Tumwater. Learn more about George Bush.

The original Bush butternut tree on his farmland is 170 years old and in declining health. South Sound historians have worked to propagate its offspring, including that tree, to preserve its genetic purity.
