Nope Janet, it isn't Stachys floridana. I have that growing all over the place on this property. Actually it was the dh who said it was the "same stuff that's all over our place" that got the whole "thing" started.
I told him it wasn't & he was being stubborn so I made him pull over so I could get some to prove I was right.
That's twice now that I have forgotten to state that I did check for any odor & there was none. I crushed a leaf & nothing, not a whiff of anything. That really surprised me.
As to how big it is..... I will have to go out tomorrow & take a photo with the tape measure to demonstrate size.
