A horizontal stem of a plant that is usually found underground, often sending out roots and shoots from its nodes. Students of Naropa University are obsessed with the rhizome, as it fulfills their dual lust for metaphor and salad.
"Rhizome, an underground stem bearing roots and flowers, and a postructuralist metaphor for nomadic traits, is a trope that Anne Waldman exploits to describe hybrid, cross-genre poetics and intuitive constellations." It also makes a decent tea.
