2-S ARENA

Stay away from this stuff!! It will hurt you, bad! This is Poison Hemlock and it looks pretty from afar,but just a little bit of this will kill you and your animals. It's also found in almost every state in America.
Symptoms can appear within 30 mins of touching it and if ingested , can attack your nervous system just as fast.
Not every white flower is poisonous and there are many flowers out there that look like this that are ok to be around.
So,how do you know if this is Hemlock? Look at the stem (pic in comment section) for purple dots/streaks
I've seen it in fields, property lines and also near drainage ditches.
