Rhizome

Rhizomes are often known as aggressive plants because they grow underground in a way that can easily take over the soil if not properly maintained. Ginger is an example of a rhizome because it grows horizontally, underground. Rhizomes are so aggressive because once they have been harvested, there is still the possibility that there could still be roots in the ground that will continue growing. The roots of the plant are very strong and they store the starches, proteins, and other nutrients that are necessary to keep the plant alive.
