Orchid tree flower?

While out on a walk in the neighborhood, I came across this pretty flower that I couldn't resist taking a shot of . . . but, I don't know if it's an Orchid tree or it's actual name. My walking friend said she didn't think so . . . for now, the name of it, remains a mystery.

I love these purple little flowers that are growing thru from our neighbors side of the fence that separates our yards. I have no idea what the name of it is though. It has the appearance of Rosemary...but I know it is not Rosemary.  Below is a full view of the flowers and branches coming thru the fence.
