Just use ghost pipes for your grayanotoxin.
Had to look that up and stumbled across this:
> The information about ghost pipe containing grayanotoxin is based on a single source from 1889. (Yes 1889, not 1989!)

They are also listed as endangered in several states. I see them with some regularity in Wisconsin, even had one in my yard a few years back.
