[Michlib-l] Help Identifying a short story reference question.

Hello! I was hoping to get some help answering a reference question for a patron that has stumped me. They are looking for a short story that was most likely published in the 1950s or 1960s. It is science fiction and is about a planet that humans land on, where the planet is controlled by a plant named "the core." She said it is about 5 pages long. It was most likely published in an anthology or magazine. At first I thought it might be "Vaster than Empires and More Slow" but that doesn't refer to the plant entity by name and was published in the 1970s. Many thanks in advance! *Jesse Cornea* Library Associate Brandon Twp Public Library 304 South Street Ortonville MI 48462 248-627-1461 *ENGAGE • EDUCATE • ENRICH • EMPOWER*
