Its stem is a stolon, which can spread along the soil surface, and then grow fibrous roots in the lower half of each leaf node, and reach into the soil. Once it grows, under the right conditions, the axils between the leaves and stems will sprout and grow new branches. In this way, it will continue to expand outward and spread its own growth space.
