Agave Americana or Century plant is a very large succulent that has become an invasive plant in my country. It is sometimes planted as a natural hedge and is quite effective for deterring intruders although I am trying to get rid of these. They have been growing without any attempt to curb their spread for the last 10 years or so and have formed an impenetrable wall at the edge of my place. It is useful but I would rather plant something indigenous in its place.
