Skyrim:Nirnroot

Nirnroot is a bright green plant normally found growing near water. They glow, making them easier to locate at night, and also emit a unique chiming sound. While in-game text claims that nirnroot does not regrow, it actually does regrow normally like other plants. A related plant is crimson nirnroot, which has nearly identical alchemical properties (only details of the Damage Health and Damage Stamina effects differ). They can be combined to make a four-effect potion.

Damage Health poisons made using nirnroot have the same strength as ones made using standard Damage Health ingredients. However, the gold value of such poisons is 12.6 times larger than standard ones. See the effect page for details.

Combinations
In terms of combinations of two ingredients, Nirnroot can be combined with 63 other ingredients.

It is categorized as a rare ingredient, meaning that most apothecary merchants have a 21% chance of carrying 1-4 samples. In addition, it may be randomly found only in rare-type apothecary's satchels. Other possible locations for already-harvested samples include:
1-2 guaranteed samples are found on several dead alchemists, including the one found at Clearpine Pond.

Notes
Nirnroot can be sold to Avrusa Sarethi at Sarethi Farm for the quest Gather Wheat.
Nirnroot and crimson nirnroot are not affected by the Alchemy perk Green Thumb, and therefore even with the perk, you still only collect a single sample from each plant. However, with the Dragonborn expansion, there are several regular nirnroot plants that can be found in Solstheim which yield multiple samples of the ingredient.

Bugs
 
 
Sometimes nirnroot becomes unharvestable; even though the sound of being picked will play, it will not be added to your inventory, nor will the plant disappear. Saving and then reloading the game will make it harvest-able again (sometimes).
