Well, I've even stumped GardenCompass with this one. It has large prickly leaves at the base and from the base has a long (like 4 ft) thickish, prickly viney stalk that kind of leans loopy-like and has branches off of it that have thin pointy clusters of leaves and ends with a bright blue flower. It's prickliness makes me think it's a weed, but I hate to yank it out if it's something good. The picture shown is of the end of one of the branches with the flower. Any help would be greatly appreciated!
