Mutated fern is a species of plant in Fallout 4 and Fallout 76.


Mutated ferns are a mutated variety of Polypodiopsida, vascular plants reproducing through spores and normally producing neither seeds nor flowers. Of limited importance before the Great War, ferns were used as decorative plants, medicine, food, and for cleaning up contaminated soils. Mutations induced by the nuclear fallout changed ferns with brownish/greenish leaves, which now are capable of blooming and producing purple flowers. These flowers are capable of consuming and neutralizing radiation and can be processed into radiation chems such as Rad-X and RadAway.[1]



Solomon the chem dealer from Diamond City will buy mutated fern flowers. The payment is a small number of caps and a random chem. Talk to him directly for the task, or listen to Shelia's holotape on the rooftop of the weapon store in Forest Grove Marsh.

Behind the scenesEdit

Ferns are real world plants of the same name. No single species of fern, alive today or extinct, has ever produced flowers, hence the 'mutation' of the mutated fern.


  1. The Sole Survivor: "Looking for a job, if you got one."
    Solomon: "Yeah, I got something. Looking for a Mutated Fern if you find any. I hear some grows out near Forest Grove Marsh. Natural radiation sucker. Be great for cooking RadX or RadAway."
