What is the main function of stolons?

Stolons serve a significant role in plant propagation and growth, particularly in aquatic environments. Their main function is to run horizontally along the sediment surface, creating a network of connections between plants. This ability to spread and establish additional shoots or roots from the nodal points allows the plant to thrive and adapt to conditions, as well as to form a perennial structure that can survive various environmental stressors.

In the context of aquatic plants, stolons can help in stabilizing substrates and facilitating the spread of vegetation across areas where it may need to re-establish or expand, thereby contributing to the overall health of the ecosystem. Their growth habit also allows for quick colonization of new areas, making them vital for both the species' longevity and habitat maintenance.
