What is this flower/weed?

Asked March 29, 2017, 4:55 PM EDT

I have attached a picture of a flower that I took in Bethesda. I'm wondering what it is, since I've never seen anything like it. I don't need the genus/species name, just what it's called and known by. Is it a weed?

This plant looks like Cleome, Spider flower. It has a tendency to self seed and become weedy.
