Rhizome Farms

"In the botanical sense, a rhizome is a root system that some plants use to spread themselves. While the roots of most plants point generally downward, the rhizome is a horizontal root system that runs parallel to the surface of the ground. The plant sends shoots up from nodes in the rhizome, creating what look like many separate plants. These seemingly unrelated individuals are actually all connected, through a system that's not immediately visible to the eye."
