No, but thanks.
This is one of two tall similar plants in my yard. I knew I was allergic to one of them but I couldn't tell which. It has to be the little spines on the stems. I wore a tee shirt yesterday and starting pulling them and immediately broke out. I went in and washed my arms, but the rash is still traceable.
I just want a name for this thing. It is pouring here now. I should stop listening to Wait! Wait! don't Tell Me and read the directions for my digital camera so I can go out when it stops raining.
