whats the weed? and jack in the pulpit

I see these all over the place this time of year, and I have no idea what it is.. :( ~and~ A while back I found a CUTE Jack in the Pulpit under some bushes. I transplanted it into a pot (I wanted to put it somewhere where I could see it) but it didn't fare that well. About a week ago it started wilting, but now I see this going on: (sorry it's a little blurry, but you get the idea.. ) What's going on with this thing? can I propagate this? thanks! PS Yes in the meantime I'm googling... :)
