“Nirnroot” quest

the-elder-scrolls-v-skyrim

Now that the game is released, this is a follow-up question to this question.

I wandered around and have found a lot of Nirnroots (they're pretty hard to miss) and they also don't seem to respawn. However, I haven't yet discovered a quest related to them like there was in Oblivion.

Do I have to talk to a specific NPC, read a book, or do something else in order to start the quest? Or is there simply none in this game?

There is indeed a Nirnroot quest:

When in Blackreach (the underground city), you'll find a quest called "A Return to Your Roots" which will task you with finding out the significance of the crimson nirnroot as well as send you on a collection quest to get a bunch of them.

Additionally, Ingun Black-Briar in Riften asks for 20 of them as part of a miscellaneous objective.

Outside of these two quests, nirnroots are used in alchemy to craft invisibility potions.
