Pampas Grass

Today we cut back our pampas grass and while working with it, hubby and I decided this would be perfect to use as a security measure.  We have two and each one was about 6 feet tall and at least 4 feet in diameter.  If you were to plant these right outside each of your windows, no burglars would be able to get in for fear of being cut and scratched by this plant.  It would also be great to keep teenagers from sneaking out.
