There is a fix for this but you do need to install a mod for it.
The quest that is supposed to trigger is called Task: Running a Fever. And this mods will fix the quest so you can do it.

I tried it and it works 100%. Damn shame you need a mod to fix it.
how bout those of us on Xbox one which has no way to allow mods?
Unfortunately support for this game ended years ago, so this will never be fixed officially.
I'm the author of the mod that fixes the quest. The interaction prompt on the plants that is supposed to start this part of the quest isn't set up correctly, so there is no point in wasting your time trying different orders to approach this quest chain or whatever else people may suggest either.
It is impossible to complete (or even start) "Task: Running a Fever" without mods.
