The healthy and hardy pioneer families dared to venture into the unknown wilderness on their drive westward in America. They could take only the necessities of life, such as guns, axes, farm tools, seeds, and other bare essentials on this hazardous journey.

Rhubarb came a long way in 4600 years of history from its native home in western China.
