Greener Than You Think

When an unscrupulous salesman sprays a dying suburban Los Angeles lawn with an untested chemical spray, it is the beginning of the end of the world. The grass begins to grow uncontrollably and riotously, ten feet height, thick, tough, impenetrable, gradually engulfing Los Angeles, then California... After reading this novel, you will never view your lawn in the same way.
