What is the function of rhizomes in plants?

Rhizomes serve the vital function of spreading the plant horizontally and acting as overwintering structures. These underground stems allow the plant to propagate effectively, enabling it to grow new shoots and roots at various points along the rhizome. This horizontal growth habit helps the plant establish itself in a broader area and can contribute to the formation of dense colonies.

Additionally, during adverse conditions, such as winter or drought, the rhizomes store energy and nutrients, assisting the plant in surviving through tough periods until favorable conditions return. While other parts of the plant play roles in photosynthesis and reproduction, rhizomes are particularly significant for vegetative propagation, ensuring the plant's continued survival and expansion in its environment.
