Do every single Nirnroot (Crimson ones too) in Skyrim always respawn?

Does the Sleeping Tree Sap always respawn?

I just started a new character and want to play without broken consequences. Thanks.

1- Yes they respawn after a couple days in-game.

2- Not sure.

Yes they do.

Nirnroot respawn with the cell. Usually 10 days.

I think I heard Sleeping Tree Sap respawn every day. But I never tested it out. But they definitely had respawned every time I went back there.

Thanks!
