Agapanthus, also known as the Lily of the Nile, has garnered some negative attention lately. Even though this is a pleasant and visually appealing plant, it is an aggressive plant and seeds often in unwanted places. It is relatively simple to stop the unwanted seeding by cutting the stems that produce the light seeds often. To get rid of this lily altogether, a simple herbicide will do the trick. Remember, if the roots have moved toward other plants and have intertwined with other root systems, it may be necessary to remove or kill the other plants as well to fully remove and kill agapanthus.
