Not Poison Ivy!

How did I know, immediately, without getting closer that there was no poison ivy in these weeds?

Does that stone-brick decayed looking old-world wall suggest anything?

There can be zero poison ivy there because this photo was taken in Italy, and there is no poison ivy, oak, or sumac anywhere in Europe or England.

Which is interesting because right from the start people did bring back samples of poison ivy to England and France, but it never got loose and grew on its own.
