I have not played Bloodmoon in a long time. And I am doing the East Empire quest where you need 5 bittergreen pedals to kill the roots. So where are they. I found one in a random ancestral tomb, but I can't find anymore. I checked so many alchemists and they seem to have every random plants except Bittergreen. So yea, anyway where are they? For the life of me I can't find anymore anywhere,

Petals... not pedals. lol

But anyways, they are very easy to find on Vvardenfell.
The quickest would be to go to the Temple in Gnisis and buy them from Zanmulk. (he always has 10 in his inventory)

thanks
