A '''swamp fern''', {{cyan|F}}, is a type of [[monster]] that appears in [[UnNetHack]]. The swamp fern is a form of [[fern]] with traits that are very similar to fungi and molds, though it is [[stationary]] rather than fully sessile or fully motile.

Swamp ferns have a "[[gaze attack]]" that causes them to generate [[Swamp fern spore (UnNetHack)|swamp fern spores]] with a {{frac|2}} chance (50%) if they are not [[cancelled]] and the [[hero]] is within roughly 10 squares of one: these spores act as a means of reproduction for the fern and will target the hero and other [[monster]]s in the dungeon—monsters that are not other ferns, fern sprouts or [[Devil's Snare]] have a mutual [[grudge]] and will attack the spores themselves to prevent ferns from spreading, per the {{sa|Encyclopedia entry|encyclopedia entry}}. Spores that explode from either their [[explosion attack]] or [[on-death explosion]] have a {{frac|3}} chance of creating another fern, with a {{frac|6}} chance of creating a full-grown swamp fern and otherwise creating a [[Swamp fern sprout (UnNetHack)|swamp fern sprout]]—their active explosion attacks also leave behind [[poison cloud]]s.

==Generation==
Randomly generated swamp ferns are always created hostile, and will not normally appear in [[Gehennom]] or [[Sheol]]. They are not a valid polymorph form. Swamp fern sprouts can [[grow up]] into swamp ferns.

Swamp ferns cannot be generated on [[ice]], [[lava]] or [[pool]]s of water by normal monster creation or the explosions of their spores, though [[muddy swamp]] squares are a valid location.

A "fern nursery" [[Random vault (UnNetHack)|random vault]] has a {{frac|2}} chance of randomly placing a hostile swamp fern within the [[room]].

Swamp ferns [[Corpseless|never leave a corpse]] upon death.

==History==
The swamp fern first appears in version 5.1.0 alongside its spore and sprout via [https://github.com/UnNetHack/UnNetHack/commit/f487c9265c47ee0754fefda2305937d6cbae2fb0 commit f487c92].

==Origin==
Ferns are a group of real plants with characteristic leaves. They are primitive, having neither seeds nor flowers; they reproduce with spores, hence the spore attack in the game.

==Encyclopedia entry==
{{encyclopedia|
These dreadful weeds have been driven to extinction on the
surface, yet deep within the dark and damp of the dungeon
they still flourish. When it detects the motion of nearby
creatures, the dungeon fern releases a deadly, poisonous
spore, which quickly detonates to propagate the species.

Residents of the dungeon have learned how not to disturb
the dungeon fern, and will attack its spores on sight to
keep them from overtaking their home.

More than one variety of this plant is known to exist.
