I had to laugh when I saw this parking lot island invaded by Imperata cylindrica (cogon grass).
It really wasn't funny, but it does illustrate the problem faced by people who suddenly find masses of cogon grass in their property.

Maintenance crews may have simply pulled individual blades out (which would have done nothing to solve the problem), or perhaps even shrugged in defeat and hoped that the invader would somehow blend in with the rest of the plants.
