Yes, the plant at the door also looks like lantana. Doubt it was part of an arrangement.
It's weird that they're so close to the door and not next the the sidewalk. It would seem
"juvenile" "immature" to cut a few lantana stems and pass them off as a "gift". Yet, there are people who do this with lantana. (There are little kids who pick mine) I wouldn't expect Nancy to do this. I wouldn't expect another homeowner to do this.
It's almost as if someone came to the door with these in their hand to lure someone out. MOO MOO
Thanks for your observation....
