A crimson nirnroot plant

Crimson Nirnroot is a special variant of nirnroot that can be found exclusively in Blackreach. It has the same alchemical properties as normal nirnroot (other than details of the two damage effects). Similar to regular nirnroot, the crimson variety makes a humming sound that lets you know when a plant is nearby.

Aside from the unique jarrin root, crimson nirnroot creates the largest magnitude damage health poisons in the game; see the alchemy effects page for full details. It also makes the largest magnitude damage stamina poisons in the game.

Assuming you eat one sample to learn the effects and use thirty for the quest, there are 13 samples to use.


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

Related QuestsEdit


  • Crimson nirnroot and regular 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.
  • Combining Nirnroot and Crimson Nirnroot will unlock all ingredient effects for both plants.
