Hi Opal,it is an Umbellifer,but which is hard to say,without a photo of the leaves,stalk etc.The Umbellifers are a family that have a lot of similar looking plants,so you need a bit more info to narrow it down to get a possible id.
Plus as you probably already know there are a few very poisonous species of Umbellifers,so caution should be the order of the day,if you are playing with these plants.
Cheers Stuart.
