It might turn out to be poisonous. If you can't precisely identify what you grow, get rid of it. To reduce contamination risk, roast it to a crisp, bleach or otherwise sterilize it. This doesn't just apply to exotic plants, but also to most plants of the family Apiaceae, as they can be hard to correctly identify and tell apart. Needless to say, many of them are noxious, poisonous or invasive, some all three of them, like the giant hogweed.
