Is it poison ivy?
 

This morning I was hunting around for a friend who showed me a plant in her flower bed (that previously had some poison ivy--now removed)...and we debated back and forth.

So I just found this site which may be helpful for gardeners here:

Lots of nice pictures and comments.

The poison ivy we treated with Round-up did die nicely, and has not returned yet. ;)
