A rhizome is a plant stem that grows horizontally beneath the soil surface. These stems develop nodes which can then shoot another stem up through the soil surface. This is a form of plant reproduction that enables a plant to spread from the "mother plant," but it can also create an invasive issue if the plant is undesirable and continues to spread by vigorous rhizomes. Bamboo, ginger and many irises reproduce and "spread" by rhizomes.
