This appeared in a pot and I just left it. It became like Jack and the beanstalk! It is about 4 feet high and got a bloom like a shaft of wheat expect instead of brown, it is greenish gray. Probaly just a weed that will spread like kudzu! LOL Would like to know what it is though.
Just a shot in the dark as I've never seen it before ~ dodder? If so, then yes, it's a weed. I've heard it's a rather NASTY one at that. Mentions of it are usually followed by the statement, "BURN IT, POT, SOIL AND ALL!" ;)
