Does anyone know how long lupine seed (russell hybrid) needs to stratified for? 2 or 3 months probably, right? I collected a ton of seeds and want to start them this spring. Normally i just sprinkle them around, but this time i didn't really know where i wanted them and would like to be able to give some away to friends and such.

Also, has anyone ever tried to propagate Black Cohosh, from what i read it seems a little tricky!

Thanks!
Sarah
