What does rhizome mean?
A rhizome is an underground plant stem, usually horizontal, that sends out roots and new shoots from points along its length. Unlike a true root, it contains nodes and can produce stems, allowing plants such as ginger, bamboo, and ferns to spread through the soil. Rhizomes may also store food and help plants survive unfavorable conditions. The word can be used figuratively for interconnected systems of people, ideas, or cultural influence that spread through branching networks rather than in a direct line. In this extended sense, a rhizome suggests steady, resilient growth and the ability to produce new activity from established connections.

- A modified underground plant stem that grows horizontally or obliquely and produces roots and shoots from its nodes.

Where does rhizome come from?
The word comes through Latin from Greek rhízōma, a stem or shoot associated with rhíza, meaning “root.” Greek botanists used the term for a stem-like underground structure from which roots and shoots arise. The modern English form entered scientific usage with the development of botanical terminology.
