The experimental plant is a rare consumable item in Fallout 4.


The basis of this experimental plant was a root found by a Brotherhood field scribe at the mouth of a river, and displayed unique chemical properties, prompting a scribe to graft it onto a hardier stock for further testing and hybridization.[1]

The result was a leafy plant with thick roots, and after being determined safe to ingest, was brewed into "an oddly good tea." Soon after, other samples of the plant began to exhibit a form of bioluminescence. The scribe deduced that the leaf must have restorative properties due to how healthy they felt, but other scribes suggested that the tea should no longer be brewed and that the plant is addictive in nature.[1]


The plant is a purple bioluminescent article with thick roots. It's been named "Glowleaf" by one of the senior scribes aboard the Prydwen. They were using it to make tea and wound up becoming addicted to the substance. After the addiction began to make them agitated with their fellow scribes, the project was terminated and the scribe was reassigned.



  • This item has no addiction effect.
  • In Survival mode, the item has no food value (similar to wild plants and fungi), and provides its Health buff regardless of whether the player is Well Fed.
  • When taken, a Mister Gutsy robot will become very displeased that the player character touched the experiments.

Behind the scenesEdit

The plant's appearance, characteristics, and preference to grow near water are a reference to the nirnroot from the Elder Scrolls series, another game series produced by Bethesda Game Studios.
