Rhizome
In botany, a rhizome is a usually-underground, horizontal stem of a plant that often sends out roots and shoots from its nodes. They are also referred to as creeping rootstalks, or rootstocks. A stolon is similar to a rhizome, but exists above ground, sprouting from an existing stem.
Many plants have rhizomes that serve to spread the plant by vegetative reproduction. Examples are asparagus, Lily of the valley and Sympodial Orchids. The spreading stems of ferns are also called rhizomes.
A tuber is a thickened part of a rhizome that has been enlarged for use as a storage organ. They are typically high in starch. An example is the common potato.
Rhizome metaphors
Carl Jung used the term "rhizome", also calling it a "myzel", to emphasize the invisible and underground nature of life:
- Life has always seemed to me like a plant that lives on its rhizome. Its true life is invisible, hidden in the rhizome. The part that appears above the ground lasts only a single summer. Then it withers away—an ephemeral apparition. When we think of the unending growth and decay of life and civilizations, we cannot escape the impression of absolute nullity. Yet I have never lost the sense of something that lives and endures beneath the eternal flux. What we see is blossom, which passes. The rhizome remains. (Prologue from "Memories, Dreams, Reflections")
Gilles Deleuze and Félix Guattari used the term "rhizome" to describe theory and research that allows for multiple, non-hierarchical entry and exit points in data representation and interpretation. In A Thousand Plateaus, they opposed it to an arborescent conception of knowledge, which worked with dualist categories and binary choices. A rhizome works with horizontal and trans-species connections, while an arborescent model works with vertical and linear connections. Their use of the "orchid and the wasp" was taken from the biological concept of mutualism, in which two different species interact together to form a multiplicity (i.e. a unity that is multiple in itself).
Jeff Vail has used it to describe a non-hierarchical structure for society.
