It can make you blind!I saw this on the Internet News today and although it has not been seen in Tennessee, It's been spotted in North Carolina and that's not too far away. The plants looks like giant Queen Anne's Lace but it is VERY bad to touch!
Read what CNN had to day about it here: CNN Hogweed Plant and here is another good article too
Here is a picture I found on Google
I don't know about you, but I'm hoping I never see one of them!
