The artist, although I'm not sure he calls himself one, is Brad Knoefler.
Brad is upset with the city of Miami (that's in Florida) because they don't remove the weeds growing around his business.
He said, "We're tired of living in a big dump overrun with weeds and trash."
Last May, Brad learned about other artists in other cities who make statements by coving things in yarn
"Yarn bombing. They draw attention to things in disgusting neighborhoods."
He was inspired.
He began walking the streets and painting the giant weeds bright colors.
The effect is beautiful.
The residents of Miami seem to enjoy the colorful weeds.
Brad is going to continue weed bombing until the city addresses his concerns.
Best of luck Brad!
