Is that only me, or is there hardly any nightshade plant around? I'm doing the vampire-cure quest right now, and i need nightshade, badly! Do you guys know places where to find some?

There should be a plant or two behind the church in Skingrad.

The Best Ingrediant (i believe its called) in Imperial City Market District sells them, along with many Mage's Guild alchemy vendors

thanks guys, found 'em. I hate it though that right after i finished the quest... i litterally fell over one of those forsaken plants on every corner :>
