Small flowers with purple, yellow and white varieties
I found these flowers in Century City, CA. Every house in the area seemed to have them in either purple, yellow or white. I'm sorry for the blurry pictures, but I took them with my phone.
That looks like lantana, which is an annual in the northeast, but in places like florida it can grow into a tree or shrub. It comes in a number of colors, including pink, orange, yellow, white, lavendar, and some are multi-colored.
